Reaction Steps

To a solution of 3-(4-fluorobenzoyl)-1,2,3,4,5,6-hexahydro-azepino[4,5-b]indole-5-carboxylic acid ethyl ester (543 mg, 1.42 mmol) in 1,4-dioxane (8 mL) was added aqueous sodium hydroxide (114 mg in 2 mL Of water). The mixture was stirred for 1 hour at 20° C. Solvent was then removed under high vacuum to give a crude product, which was redissolved in water and acidified with AcOH. Solid was collected by filtration and washed with water and dried under high vacuum to give 3-(4-fluorobenzoyl)-1,2,3,4,5,6-hexahydro-azepino[4,5-b]indole-5-carboxylic acid (421 mg, 84%); MS (ES): 353 (MH+).
