Reaction Steps
A round-bottomed flask was charged with Boc-D-alanine (1.0 g, 5.29 mmol) and N,O-dimethylhydroxylamine hydrochloride (670 mg, 6.87 mmol). DMF (12 ml) was added followed by N,N-diisopropylethylamine (2.4 ml, 13.7 mmol) and HATU (2.21 g, 5.81 mmol). The yellow suspension was stirred at room temperature for 48 h. The reaction mixture was quenched with water and petroleum ether was added. The resulting suspension was filtered, washed with water and petroleum ether and dried under high vacuum to afford 1.05 g (85%) of [(R)-1-(methoxymethyl-carbamoyl)-ethyl]-carbamic acid tert-butyl ester as a white powder.
