To ethyl 1-benzyl-6-(2-(1-methyl-1H-imidazole-2-sulfonamido)ethoxy)-2,3-dihydro-1H-inden-2-ylcarbamate (26.7 mg, 0.054 mmol; see example 196) was added 2N potassium hydroxide in ethanol (4 mL, 8.00 mmol) and stirred at 90° C. for 1 h. 50% brine was added and extracted twice with dichloromethane. The combined organic layers were washed with brine, dried, filtered and evaporated to obtain a clear oil. Added 2N hydrochloric acid/diethyl ether and stirred at room temperature for 2 h, filtered, washed with diethyl ether and dried to obtain N-(2-(2-amino-3-benzyl-2,3-dihydro-1H-inden-5-yloxy)ethyl)-1-methyl-1H-imidazole-2-sulfonamide hydrochloride as a white solid. m=20.2 mg (54%)
