Reaction Steps

To a solution of benzyl [(1R)-1-cyanoethyl]carbamate (2.52 g, 12.3 mmol) in ethanol (30 ml) was added hydroxylamine hydrochloride salt (0.90 g, 13.0 mmol) and triethylamine (3.43 ml, 24.6 mmol) and the mixture heated to 75° C. After 16 h, the solution was concentrated and the residue was dissolved in 200 mL of dichloromethane. The mixture was washed with 100 mL of saturated aqueous sodium bicarbonate (2×) and brine (100 mL). The combined organic extracts were dried over sodium sulfate, filtered and concentrated to give benzyl [(1R,2Z)-2-amino-2-(hydroxyimino)-1-methylethyl]carbamate (2.9 g). MS 238.2 (M+1).
