실험 절차
Compound of example 4 (0.500 g, 2.18 mmol) was heated in chloroacetyl chloride (2 mL) at a temperature in the range of 100-110° C. for 4 hours. The reaction mixture was cooled, poured over ice water, basified With ammonia solution, and extracted with ethyl acetate (3×60 mL). The organic layer was washed with brine, dried over sodium sulfate and concentrated. The crude product obtained was purified over silica gel using ethyl acetate/petroleum ether (35%-50%) as eluent, and the pure fractions were concentrated and crystallized using chloroform/ petroleum ether, to obtain the title compound.
