Reaction Steps

Through a solution of 3,4-difluorobenzaldehyde (25.0 g, 0.18 mol) in MeOH (500 mL) in a round bottom flask was bubbled ammonia gas for two hours at room temperature The flask was then cooled to 0° C. and trimethylsily]L cyanide (1.3 eq., 0.23 mmol) was then added slowly. The reaction mixture was stirred for 2 hours when TLC analysis indicted that the reaction was complete (Rf=0.35, 3:2 hexane/EtOAc). Solvent was removed in vacuo and the residue was subjected to flash column chromatography on silica gel to obtain 25.0 g (81%) of amino-(3,4-difluorophenyl)-acetonitrile as a yellow syrup.
