반응 단계
A solution of 4-[N-(tert-butoxycarbonyl)amino]-cyclohexane carboxylic acid (11.95 g, 49.0 mmol), O,N-dimethylhydroxylamine (4.88 g, 50.0 mmol), DCC (9.60 g, 50 mmol) and triethylamine (5.06 g, 50.0 mmol) in DMF (150 mL) was stirred at room temperature overnight. Water (500 mL) was added and the mixture was extracted with CHCl3. The organic phase was washed with water, dried and concentrated under reduced pressure. Purification by flash chromatography (hexane/EtOAc 1:1) gave [4-(methoxy-methyl-carbamoyl)-cyclohexyl]-carbamic acid tert-butyl ester (8.50 g, 61%).
