Example 100 3-cyano-A-[10,ll-dichloro-4-oxo-3-(trifluoromethyl)-2,5,7-triazatricyclo[6.4.0.02’6]dodeca- l(8),6,9,ll-tetraen-3-yl]benzamide (ABR 239453) To a stirred solution of 3-cyanobenzamide (650 mg, 4.45 mmol) in DMF (7 mL) was added pyridine (378 mu, 4.45 mmol) followed by ethyl 3,3,3-trifluoro-2-oxopropanoate (590 mu, 4.45 mmol) at room temperature under argon. The reaction mixture was stirred at room temperature for 1 h. Thionyl chloride (323 mu, 4.45 mmol) was added at 0¡ãC. The reaction mixture was then stirred at room temperature for a further 16 h and before the reaction mixture was concentrated. The acyl intermediate that remained was dissolved in DMF (5 mL) under argon. 5,6-Dichloro- lH-l,3-benzodiazol-2-amine (674 mg, 3.34 mmol) and triethylamine (934 mu, 6.67 mmol) were added and the reaction mixture was stirred at room temperature for 16 h. The reaction mixture was diluted with water and extracted with EtOAc. The organic phase was washed with brine, dried (Na2SC>4), filtered and concentrated. The crude product was purified by silica chromatography, using 3percent MeOH in DCM as eluent. Further purification was carried out by trituration in DCM/MeOH and then pentane to afford the title compound as a white solid (25 mg, 1percent).

According to the analysis of related databases, 3441-01-8, the application of this compound in the production field has become more and more popular.

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 3441-01-8, name is 3-Cyanobenzamide, A new synthetic method of this compound is introduced below., Recommanded Product: 3-Cyanobenzamide

Under argon, tert-butyl 4-(10-bromo-2-oxo-l,2-dihydropyrimido[l,2-b]indazol-4-yl)piperidine-l- carboxylate (200 mg, 447 muiotaetaomicron), 3-cyanobenzamide (163 mg, 1.12 mmol), Tripotassium phosphate (133 mg, 626 muiotaetaomicron), tBuBrettPhos (13.0 mg, 26.8 muiotaetaomicron), and tBuBrettPhos Pd G3 (22.9 mg, 26.8 muiotaetaomicron) were dissolved in l-Methoxy-2-propanol (5.0 ml, 52 mmol). The mixture was stirred at 110 ¡ãC for 16 h and then purified via reverse phase chromatography (Method: Reprosil C18; 10 muiotaeta; 125×30 mm / flow: 50 ml/min / solvents: A = water (0,01percent formic acid), B = Acetonitrile / gradient 0.00-4.25 min = 20percentB, 4.50min = 30percentB, 19.00-22.50min = 100percentB, 22.75-25.00min = 20percentB) which afforded the product after drying in vacuo. The obtained amout was 130 mg (100 percent purity, 57 percent of theory). LC-MS (Method 1): Rt = 1.15 min; MS (ESIpos): m/z = 513 [M+H]+

The synthetic route of 3441-01-8 has been constantly updated, and we look forward to future research findings.

Some common heterocyclic compound, 3441-01-8, name is 3-Cyanobenzamide, molecular formula is C8H6N2O, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Quality Control of 3-Cyanobenzamide

General procedure: Amides (1 mmol) and Lawesson’s reagent (490 mg, 1.2 mmol) were added to dry THF (15 mL). The reaction mixture was stirred at room temperature for 1 h, or heated under reflux for 5 h in the case of the 4-nitro derivative. The solvent was evaporated under reduced pressure and the residue was partitioned between aq NaHCO3 (25 mL) and ethyl acetate (25 mL). The organic solvent was separated and dried over anhydrous MgSO4. The crude product was further purified by silica gel flash chromatography, using hexane-ethyl acetate (4:1), to yield the corresponding thioamides as yellow solids (42-60percent). 4-Nitrothioamide (2ff),38 4-cyanothiobenzamide (2gg)39 and 3-cyanothiobenzamide (2hh),40 3-methoxythiobenzamide (2ii)41 have been previously reported.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3441-01-8, its application will become more common.
