Reaction Steps

Into a solution of 22.6 g (0.181 mol) of 4-hydroxy benzaldehyde dissolved in 75 mL tertiary butanol, was added 38.5 g (0.278 mol) of potassium carbonate in 10 min. Reaction mixture was refluxed for 1 hr. and 15 g (0.06 mol) of 2-bromo-1-(5-ethyl-pyridin-2-yl)-ethanol dissolved in 75 mL tertiary butanol was added slowly in one hr. Reaction mixture was refluxed further for 10 hr, and at 25° C. poured into excess of water. Product was extracted with toluene. Subsequent concentration under reduced pressure and purification gave the desired product. Yield of the product was 12.37 g (70%). m.p. 80° C.
