Reaction Steps

A mixture of 11 g of 2-hydroxy-3-iodo benzaldehyde, 8.6 g of (3-methoxy-phenyl) acetylene and 150 ml of pyridine was refluxed for 45 minutes and then allowed to return to ambient temperature. Ethyl acetate was added, and washing was carried out with an acid solution, followed by drying and concentrating to obtain 16 g of product which was chromatographed on silica (eluant: hexane-isopropyl ether (7-3)) to obtain 9 g of the desired product melting at 55° C. to 60° C.
