Procedure

In this step, allyl chloride (23.3 grams, 0.31 mol) was added to a stirred solution of N-(3-cyclopentyloxy-4-methoxyphenylacetyl)-2-hydroxy-5-chloroaniline (78 grams, 0.21 mol) in ethanol (600 millilters) and 1N NaOH in methanol (213 milliters). The mixture was heated under reflux for 8 hours and then diluted with water and extracted twice with ethyl acetate. Evaporation of the ethyl acetate and crystallization of the residue from methanol gave 56.4 grams (65%) of the title compound, mp 75°-76.5°.
