Reaction Steps
1-Naphthol (2.16 g, 15 mmol), 4-benzyloxy-3-bromo-5-methoxy-benzaldehyde (4 g, 12.5 mmol) and malononitrile (825 mg, 12.5 mmol) were taken in 30 ml ethanol at room temperature, charged with piperidine (200 μl) and then stirred at 80° C. under LC-MS control till the reaction was complete. The reaction mixture was then cooled down to room temperature, diluted with 60 ml water and stirred for about 2 h at room temperature. Thus formed precipitates were collected by filtration, washed with 1:1 mixture of ethanol/water and dried under high vacuum yielding pure solids of the title compound (6.0 g, 11.7 mmol, 93.5%).
