Reaction Steps

3,4-Methylenedioxyphenol (166 mg, 1.2 mmol), 4-allyloxy-3-bromo-5-methoxy-benzaldehyde (271 g, 1 mmol) and ethyl cyanoacetate (113 mg, 1 mmol) were taken in 7 ml ethanol at room temperature, charged with piperidine (50 μL) and then stirred at 80° C. under LC-MS control till the reaction was complete. The reaction mixture was cooled down to room temperature, diluted with 10 ml water, stirred for 2 h at room temperature, solids were collected by filtration, washed with 1:1 mixture of ethanol/water and dried (239 mg, 0.47 mmol, 47%).
