Sodium Bicarbonate → HCID 71711171, compound

Participants

Reaction Steps

A solution of tert-butyl 4-(1-((2S,4R)-4-(2-chlorophenylsulfonyl)-2-(1-cyanocyclopropylcarbamoyl)pyrrolidine-1-carbonyl)cyclopropyl)piperazine-1-carboxylate (367 mg, 605 μmol) in formic acid (6.05 mL) was stirred at room temperature for 5 hours. The reaction was diluted with water under ice cooling and set to pH 7-8 slowly by first adding saturated aqueous sodium hydrogen carbonate solution and then with solid sodium hydrogen carbonate. The reaction was extracted three times with methylenechloride. The combined organic layers were washed with saturated aqueous sodium chloride solution, dried over sodium sulfate, filtered and the solvent was evaporated under reduced pressure to yield the title compound as a light yellow foam (224 mg, 73%). MS ISP (m/e): 506.1/508.2 (100/45) [(M+H)]+.
