참여 물질

반응 단계

To a solution of 3-methylbutane-1,3-diol (2.13 mL, 20 mmol) in pyridine (20 mL) at 0° C. was added para-toluenesulfonyl chloride (3.8 g, 20 mmol) in pyridine (10 mL) drop-wise over 15 minutes. This mixture stirred at ambient temperature for 3 hours and 35 mL H2O was added and the mixture was extracted with ethyl acetate (2×50 mL). The combined organics were washed with H2O (2×50 mL), dried over MgSO4, filtered, concentrated under reduced pressure and dried under vacuum (˜1 mm Hg) to afford the title compound. MS (ESI) m/z 276 (M+18)+.
