実験手順
In a round-bottomed flask charged with tert-butyl(cis-3-hydroxycyclobutyl)carbamate (1.11 g, 5.93 mmol) and triethylamine (2.474 ml, 17.79 mmol) was added CH2Cl2 (12 ml). methanesulfonyl chloride (0.505 ml, 6.52 mmol) was added dropwise via syringe at −20° C. over 5 min. The reaction mixture was stirred at room temperature for 30 min, then diluted with water (15 mL) and extracted with CH2Cl2(2×). The organic extract was washed with saturated NH4Cl and dried over MgSO4. It was filtered and concentrated in vacuo to give cis-3-((tert-butoxycarbonyl)amino)cyclobutyl methanesulfonate (1.64 g, 6.1 mmol, 100% yield) as a off-white solid.
