Reaction Steps

0.44 g (0.0044 mol) triethyl amine was added to a solution of 1 g (0.0036 mol) 4-[2-(5-ethyl-pyridin-2-yl)-2-hydroxy-ethoxy]-benzaldehyde and 0.7 g (0.0036 mol) tosyl chloride dissolved in 25 mL dichloromethane at 0-5° C. Reaction mixture was stirred at 0-5° C. for 4 hr. Progress of the reaction was monitored by TLC and after completion of reaction, substantial work-up in excess water yielded the desired product. Yield of the product was 1 g (70%).
