(4-Isopropyl-1,3-thiazol-2-yl)methanol (10 g, 63.6011 mmol) dissolved in dichloromethane (60 ml) was added with thionyl chloride (7 ml, 95.40 mmol) under ice cooling, and then the reaction solution was returned to room temperature and stirred for 20 minutes. The reaction solution was concentrated under reduced pressure, and the residue was subjected to azeotropy with toluene and then diluted with diethyl ether, and further neutralized with saturated aqueous sodium hydrogencarbonate. The organic layer was washed with saturated brine, then dried over magnesium sulfate and concentrated under reduced pressure. The title compound was obtained as the residue without purification (11 g, 100%).
