To a solution of 82 mg of 2-ethyl-4-hydroxymethylpyridine and 79 mg of triethylamine in dichloromethane (2 mL) was added 82 mg of methanesulfonyl chloride, followed by stirring at room temperature for 1 hour. It was purified by PLC (chloroform:methanol=10:1), dissolved in ethyl acetate, washed with an aqueous sodium bicarbonate solution and then with brine and then dried over anhydrous sodium sulfate, and the solvent was removed by evaporation to obtain 47 mg (yield 36%) of a title compound as a yellow oily substance.
