실험 절차

To a solution of Racemate-ethyl 3-(tert-butoxycarbonylamino)-4-hydroxycyclohexanecarboxylate (12.0 g, 42 mmol) and triethylamine (12.7 g, 126 mmol) in dichloromethane (150 mL) was added methanesulfonyl chloride (9.5 g, 84 mmol) dropwise at 0° C., and the mixture was stirred at 0° C. for 3 hours. The solution was washed with water (100 mL×3) and brine, dried over anhydrous sodium sulfate, filtered and concentrated to afford the title compound (15 g, crude) as a yellow oil. MS (ES+) C15H27NO7S requires: 365, found: 266 [M+H−100]+.
