실험 절차

To ethyl 1-benzyl-6-(2-(1-methyl-1H-imidazole-4-sulfonamido)ethoxy)-2,3-dihydro-1H-inden-2-ylcarbamate (33 mg, 0.066 mmol; see example 195) 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 m=27.3 mg. Added 2N hydrochloric acid/diethyl ether and stirred at room temperature for 2 h, filtered, washed with diethyl ether and dried to obtain the desired product as a white solid. m=8.6 mg (28%)
