Related Products of 53312-78-0,Some common heterocyclic compound, 53312-78-0, name is 3-Amino-5-chlorobenzonitrile, molecular formula is C7H5ClN2, 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.
Representative of synthesis of ( N-(3-(3-aminopropanamido)-5-chlorobenzyl)-6 – chloro-1, 3, 4,9-tetrahydro-2H-pyrido[ 3, 4-b lindole-2-carboxamide : To a solution of 3-amino-5- chlorobenzonitrile (1.0 g, 6.55 mmol,1.0 eq), 3-((tert-butoxycarbonyl) amino) propanoic acid (1.24 g, 6.55 mmol,1.0 eq) and HATU (2.98 g, 7.86 mmol,1.2 eq) in DMF (15 mL) was added DIEA (2.5 g,19.65 mmol, 3.0 eq) at 25 C. Then the reaction mixture was stirred at 25 C for 1 hr. TLC showed 3 -amino-5 -chlorobenzonitrile was consumed completely and one new spot formed. The reaction mixture was diluted with water (100 mL) and extracted with ethyl acetate (100 mL x 3). The combined organic phase was concentrated in vacuo. The residue was purified by silica gel column chromatography (eluent: PE/EA = 5/1 to 3/1) to give tert-butyl (3 -((3- chloro-5-cyanophenyl) amino)-3-oxopropyl) carbamate (1.5 g, yield: 70.8%) as a yellow solid. NMR (400 MHz, DMSO-^) d 10.42 (s,1 H), 7.98 (d, J = 1.6 Hz,1 H), 7.92 (s,1H), 7.71 -7.67 (m,1 H), 6.90 (t, J = 5.2 Hz,1 H), 3.32 (s, 2 H), 3.22 (dd, J = 12.8, 6.8 Hz, 2 H),1.37 (s, 9 H). [0234] To a solution of tert-butyl (3-((3-chloro-5-cyanophenyl) amino)-3-oxopropyl) carbamate (500 mg,1.54 mmol,1.0 eq) in methanol (10.0 mL) was added Raney-Ni (180 mg, 3.08 mmol, 2.0 eq) and NH3·H20 (0.1 mL). The reaction was stirred at 25 C for 4 hrs under . LCMS showed the complete consumption of the starting material, and the desired product mass was detected. The reaction mixture was filtered and concentrated in vacuo to give tert-butyl (3- ((3-(aminomethyl)-5-chlorophenyl) amino)-3-oxopropyl) carbamate (460 mg, yield: 90.9%) as a yellow oil. LCMS: [M+H] + = 328.1
The synthetic route of 53312-78-0 has been constantly updated, and we look forward to future research findings.
