反応手順

To a partial suspension of (1-methyl-1H-pyrazol-4-yl)methanol (75 mg, 0.67 mmol) in CH2Cl2 (4 mL) at 0° C. was added triethylamine (0.19 mL, 1.34 mmol) followed by methanesulfonyl chloride (57 μL, 0.74 mmol). The cloudy reaction mixture was stirred at 0° C. for 1 h then quenched with water and extracted with CH2Cl2. The organics were dried over MgSO4 and concentrated to give 110 mg of methanesulfonic acid 1-methyl-1H-pyrazol-4-ylmethyl ester a colorless oil which was used without further purification.
