To a solution of 1.31 g (7.48 mmol) of methyl 3-(cyanomethyl)benzoate in 31 mL of THF stirred at −10° C. was slowly added 710 mg (18.7 mmol) of sodium borohydride followed by 1.44 mL (18.7 mmol) of trifluoroacetic acid. The mixture was warmed to 22° C. and stirred for about 16 h. About 100 mL of water was carefully added to the mixture (gas evolution). The mixture was extracted with ethyl acetate (5×50 mL). The organic phase was washed with brine, dried (Na2SO4), filtered and evaporated to give methyl 3-(2-aminoethyl)benzoate which was used in the next step without purification.
