Participants

Reaction Steps

Add sodium cyanoborohydride (957 mg, 15.24 mmol) to a stirred solution of 4-cyanobenzaldehyde (500 mg, 3.81 mmol), 2,2,2-trifluoroethylamine (0.3 mL, 3.81 mmol) and acetic acid (0.44 mL, 7.62 mmol) in methanol (5 mL). Stir the mixture overnight at room temperature. Partition the mixture between 1N aqueous NaOH and DCM. Extract the aqueous phase twice with DCM. Dry the combined organic extracts over MgSO4, filter and concentrate in vacuo to obtain the desired intermediate (749 mg, 92%) suitable for use without further purification. MS (ES+) m/z: 215 (M+H)+.
