Procedure
3-Isocyanatobenzonitrile (202 mg, 1.4 mmol) was added in one portion to a solution of 22B (320 mg, 1.4 mmol) in methylene chloride (10 mL). After stirring overnight the reaction mixture was concentrated in vacuo and purified by flash chromatography (0 to 100% EtOAc in hexanes) to yield 22C (430 mg, 88%) as a clear oil. MS (ESI) m/z 371.92/373.92 (M+H)+.
