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