Reaction Steps

Sodium azide (87 mg) was added to a solution of 552 mg of 7-[(2S,4R)-4-methanesulfonyloxy-1-(4-nitrobenzyloxycarbonyl)pyrrolidin-2-yl]carbonylimidazo[5,1-b]thiazole in 5 ml of DMF, and the mixture was stirred at 100° C. for 13 hr. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate, followed by washing three times with brine. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was then removed by distillation to give 474 mg of a crude product of 7-[(2S,4S)-4-azido-1-(4-nitrobenzyloxycarbonyl)pyrrolidin-2-yl]carbonylimidazo[5,1-b]thiazole.
