반응 단계
A mixture of 1.00 g (2.60 mmol) of the starting material I, 0.94 g (5.19 mmol) of ethyl 2-bromopropionate and 10 ml of dimethylformamide was stirred at 80-90° C. for 2 h. After diluting with water the obtained crude product was purified by refluxing in 15 ml of ethanol to yield 1.08 g (95%) of the title compound; Mp.: 213-214° C.
