反応手順
A mixture of 1.00 g (2.60 mmol) of the starting material I, 2.54 g (12.89 mmol) of bromoacetaldehyde diethyl acetal and 10 ml of dimethylformamide was stirred at 80° C. for 40 min. Then the reaction mixture was diluted with water and the crude product obtained was recrystallized from ethanol to yield 0.85 g (80%) of the title compound. Mp.: 145-150° C.
