The synthetic route of 77326-36-4 has been constantly updated, and we look forward to future research findings.
Application of 77326-36-4,Some common heterocyclic compound, 77326-36-4, name is 2-Amino-6-fluorobenzonitrile, molecular formula is C7H5FN2, 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.
Example 2;: N,N-Dimethyl-2-cyano-3-methoxyphenylsulfonamide (Compound No. 2); 2.1 : 2-Amino-6-methoxybenzonitrile; EPO A solution of 70 g (0.5 mol) of 2-amino-6-fluorobenzonitrile (prepared, e.g. according to US 4,504,660) in 250 ml of N,N-dimethylformamide was prepared, and a solution of 30.6 g (0.55 mol) of sodium methoxide in 70 ml of methanol was added dropwise at room temperature while stirring. The mixture was then refluxed for 5 hours with stirring. The completion of the reaction was monitored by TLC. An additional 25 g of sodium methoxide in 35 ml methanol were added and the reaction mixture was refluxed for an additional 4 hours while stirring. The reaction mixture was concentrated under reduced pressure. The resulting residue was triturated with water, filtered off with suction and the solids obtained were dissolved in ethyl acetate. The resulting solution was concen- trated in vacuo. The obtained residue was triturated with petroleum ether and filtered off with suction. Yield: 48 g (63% of theory) of a brownish solid having a melting point of 143-146C.
