Procedure

To a solution of BrCN (0.11 g, 1.1 mmo) in MeOH (10 mL) at 0° C. was added solid KOAc (0.32 g, 3.3 mmol) and a solution of aniline (0.1 mL, 1.1 mmol) in MeOH (1 mL). The reaction was stirred for 3 hours then partitioned with water (15 mL) and dichloromethane (25 mL). The organic layer was separated, washed with brine, dried over magnesium sulfate, filtered and reduced to dryness to afford N-phenylcyanamide, which was immediately used without purification.
