Reaction Steps

A solution of α-isopropyl-4-difluoromethoxyphenylacetyl chloride (4.58 mmol) in ether (5 ml) is added to an ether (20 ml) solution of α-cyano-m-phenoxybenzyl alcohol (4.58 mmol) and pyridine (0.5 ml). The mixture is stirred overnight and filtered. The filtrate and the washings are evaporated and the residual oil is purified on 5×20 cm silica gel plates using 1:1 methylenechloride-hexane as eluent. The band in the silica gel plate is extracted with ether and evaporated to give the desired ester as an oil.
