Into a 25-mL round-bottom flask contained a solution of tert-butyl N-(4-[[(3R)-3-[2-[(tert-butyldimethylsilyl)oxy]ethyl]-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yl]oxy]-1-ethylcyclohexyl)carbamate (240 mg, 0.42 mmol, 1.00 equiv) in dichloromethane (10 mL) was added hydrochloric acid (5 M, 1 mL) and the resulting solution was stirred for 5 hr at RT. The reaction was then quenched saturated aqueous sodium bicarbonate, extracted with 3×40 mL of dichloromethane. The combined organic layers were washed with brine, dried over anhydrous sodium sulfate and concentrated under vacuum to give 120 mg (80%) of 2-[(3R)-12-[(4-amino-4-ethylcyclohexyl)oxy]-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-3-yl]ethan-1-ol as a yellow oil. MS: 362 [M+H]+.
