Procedure

4-(3-Cyclopentyl-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-yloxymethyl)-benzoic acid methyl ester (E88) (3.1 g, 8.1 mmol)) was dissolved in a mixture of methanol (90 ml), 2N sodium hydroxide (12 ml) and water (30 ml). The resulting mixture was stirred at 60° C. for 4 hours and then cooled to room temperature. The mixture was concentrated in vacuo to remove the organic solvents and then acidified to pH 6 (2N hydrochloric acid). The resulting precipitates were filtered, washed with water and dried under vacuum to afford the title compound (E89); MS (ES+) m/e 366 [M+H]+.
