Reaction Steps

In a mixture of methylene chloride (1 mL) and pyridine (2 mL) was dissolved 2-[2-(2-chlorophenyl)-5-isopropyloxazol-4-yl]ethanol (159 mg, 0.598 mmol). Under cooling with water, to the solution was added p-toluenesulfonyl chloride (125 mg, 0.658 mmol). The mixture was stirred for 5 hours. The reaction mixture was poured into 1N HCl and extracted with chloroform. The organic layer was successively washed with water, saturated aqueous sodium hydrogen carbonate and saturated brine, dried over sodium sulfate, filtered, and concentrated. The residue was purified by flash chromatography on silica gel (hexane/ethyl acetate=2/1), to obtain the desired compound (123 mg, 49%).
