Reaction Steps

Sodium hydride (47 mg of 60% oil dispersion, 1.2 mmol) was added to a solution of 4-(benzyloxycarbonylamino)-1-(tert-butoxycarbonyl)piperidine (200 mg, 0.598 mmol) from Procedure 4, Step C and allyl bromide (0.251 mL, 351 mg, 2.9 mmol) in 2.0 mL of DMF, and the reaction was stirred overnight at rt. The reaction mixture was poured into 20 mL of water and extracted with 3×20 mL of ethyl ether. The combined organic layers were washed with 30 mL of brine, dried over sodium sulfate, and evaporated. The crude product was purified by FC on silica gel, eluting with 20% ethyl acetate in hexane, to give 246 mg of the title compound as a viscous oil.
