反応手順
A mixture of 1.00 g (2.6 mmol) of the starting material I, 1.19 g (7.78 mmol) of methyl bromoacetate and 10 ml of dimethylformamide was stirred at 80-90° C. for 1 h. After diluting with water the obtained crude product was purified by refluxing in methanol to yield 1.00 g (91%) of the title compound; Mp.: 218-220° C.
