Reaction Steps

To a solution of (3R)-3-[2-[(tert-butyldimethylsilyl)oxy]ethyl]-12-[[4-(morpholin-4-yl)cyclohexyl]oxy]-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraene (850 mg, 1.64 mmol, 1.00 equiv) in methanol (20 mL) was added hydrochloric acid (2 M, 1.0 mL) and the resulting mixture was stirred for 1 hr at 0° C. in a water/ice bath. After completion, the reaction was quenched with sodium bicarbonate (sat.) and extracted with 3×80 mL of ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate and concentrated under vacuum. The residue was purified on a silica gel column with chloroform/methanol (15:1) to afford 2-[(3R)-12-[[4-(morpholin-4-yl)cyclohexyl]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 (600 mg, 91%) as a colorless oil. MS (ES): m/z 404 [M+H]+.
