Yield:25978-74-9 79%

Reaction Conditions:

with copper(l) cyanide in N,N-dimethyl-formamide at 140; for 6 h;

Steps:

8.2 Step 2: Preparation of 3-cyano-4-methoxybenzoic acid methyl ester
To a solution of compound y (1.1 g, 4.4 mol) in dimethylformamide (10 mL) was added cuprous cyanide (1.2 g, 13.2 mmol). And the mixture was heated to 140 ° C for 6 hours. The reaction system was cooled and then ethyl acetate (25 mL) was added. The extracted organic phase was washed with saturated brine and the concentrated residue was dried and concentrated by flash column chromatography (petroleum ether: ethyl acetate = 10: 1) to give a white solid Compound z: Methyl 3-cyano-4-methoxybenzoate (662 mg, yield 79%).
