Reaction Steps

2-Naphthol (170 mg, 1.2 mmol), 3,4,5-trifluorobenzaldehyde (160 mg, 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 water to about 15 ml, stirred for 1 h, solids were collected by filtration, washed with 60% aq ethanol and dried (346 mg, 0.86 mmol, 86%).
