Reaction Steps

2-Chloro-α,α,α-trifluoro-p-tolyl-3-(1-carbethoxyethoxy)-4-nitrophenyl ether (8.6 g. 0.02 mol), potassium hydroxide 86% (2.6 g. 0.04 mol), ethanol (8 ml.), dioxane (8 ml.), and water (100 ml.) are heated at 90°-95° C. for 30 minutes. Ether (200 ml.) and water (200 ml.) are added and the mixture acidified with dilute sulfuric acid, the water layer extracted three times with ether (200 ml. each), dried, and the ether removed to give 2-chloro-α,α,α-trifluoro-p-tolyl-3-(1-carboxyethoxy)-4-nitrophenyl ether (6.4 g. 79%) m.p. 108°-109° C.
