Reaction Steps

Part A. Benzyl (S)-2-cyanopyrrolidine-1-carboxylate (500 mg, 2.17 mmol) was dissolved in aqueous ethanol (3 m-L) and water (1 mL). Hydroxylamine hydrochloride (152 mg, 2.17 mmol) and Na2CO3 (115 mg, 1.08 mmol) were added and the reaction mixture heated to 100° C. for 1 h. The ethanol was removed and the aqueous residue was extracted with dichloromethane (3×25 mL), dried over Na2SO4 decanted and concentrated yielding benzyl (S)-2-(N-hydroxycarbamimidoyl)pyrrolidine-1-carboxylate as a pale yellow gum (428 mg, 75% yield): HPLC (method 1) tR=1.40 min, Purity 76%; LCMS (method 4) tR=0.81 min, m/z 264 (M+H).
