Reaction Steps

Sodium bi carbonate (0.204 g, 2.9 mmol) was dissolved in EtOH (10 mL) and water (10 mL). Hydroxylamine hydrochloride (0.204 g, 2.9 mmol) was added at 25° C. A solution of (cyano-cyclopropylmethyl-methyl-methyl)-carbamic acid tert-butyl ester (3) (0.7 g, 2.67 mmol) in ethanol (5 mL) was added thereto and the resulting reaction mixture was heated at 80° C. for 12 hours. After evaporation of solvents, the residue was dissolved in ethyl acetate (30 mL) and then filtered. The filtrate was concentrated in vacuo. The residue was purified by chromatography (Combi-Flash, 40 g, 5:95 ethyl acetate/n-hexane) to give the title compound (0.45 g, 65%) as white solid; LC-MS (ELSD peak area, ESI) 100%, 258.2 [M+H]+.
