Procedure

To a stirred solution of 5 g (0.018 mol) 4-[2-(5-ethyl-pyridin-2-yl)-2-hydroxy-ethoxy]-benzaldehyde dissolved in chloroform was added 2.63 g (0.022 mol) thionyl chloride at 55-60° C. Reaction mixture was refluxed for 1 hr. Progress of the reaction was monitored by TLC and after completion of reaction, subsequent work-up in alkaline water yielded 4 g (75%) of the desired product.
