実験手順
Methane sulfonyl chloride (5.2 mL, 68.7 mmol) was added drop wise to an ice cooled solution of {1-[(benzyloxy)methyl]cyclopropyl}methanol (Compound 63E, 11 g, 57.2 mmol) and triethylamine (15.5 mL, 114 mmol) in dichloromethane (50 mL). The reaction mixture warmed to RT and allowed to stir overnight. The reaction mixture was filtered to remove solids. The filtrate was washed with saturated sodium bicarbonate solution followed by brine, dried over magnesium sulfate, filtered and concentrated to give 12 g (77%) of the desired product as light yellow oil which was used without further purification. 1H NMR (400 MHz, CDCl3) δ 7.25-7.41 (m, 5H), 4.58 (s, 2H), 4.21 (s, 2H), 3.42 (s, 2H), 2.96 (s, 3H), 0.61-0.75 (m, 4H).
