Participants

Reaction Steps

NaH (346 mg, 8.7 mmol, 60% dispersion in oil) was added in one portion to a solution of 3-isocyanatobenzonitrile (567 mmol, 3.9 mmol) and 62E (960 mg, 3.9 mmol) in THF (40 mL) and the cooling bath was removed. After stirring for 2 h at ambient temperature 1.0 N citric acid (50 mL) was added and the mixture was extracted with diethyl ether. The combined organics were washed with brine, dried over Na2SO4 and concentrated in vacuo. The crude residue was purified by flash chromatography (0% to 60% EtOAc in hexanes) to yield 62F (611 mg, 50%) as a pale, yellow solid. MS (ESI) m/z 411.0/413.0 (M+H)+.
