Reaction Steps

Into a 10-mL round-bottom flask was placed a solution of tert-butyl N-(4-[[(3R)-3-[(2R)-2-carbamoyl-2-hydroxyethyl]-7-thia-9,11-diazatricyclo[6.4.0.0^[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yl]oxy]cyclohexyl)-N-methylcarbamate (0.7 g, 1.16 mmol, 1.00 equiv) in dichloromethane (10 mL) at 0° C. under nitrogen. Then hydrochloric acid (12 M, 2.0 mL) was added and the resulting solution was stirred for 5 h at 0° C. After completion of the reaction, the solvents were evaporated under reduced pressure. The residue was neutralized with 2 M aqueous sodium bicarbonate and extracted with 3×60 mL of dichloromethane. The organic layers were combined and washed with brine, dried over anhydrous sodium sulfate and concentrated under vacuum to give 400 mg (crude) of (2R)-2-hydroxy-3-[(3R)-12-[[4-(methylamino)cyclohexyl]oxy]-7-thia-9,11-diazatricyclo[6.4.0.0^[2,6]]dodeca-1(8),2(6),9,11-tetraen-3-yl]propanamide as a yellow oil. 1H NMR (300 MHz, CD3OD): δ 8.46 (s, 1H), 5.30 (m, 1H), 4.08 (m, 1H), 3.66 (m, 1H), 3.19-3.12 (m, 1H), 3.02-2.96 (m, 1H), 2.74-2.25 (m, 9H), 2.13-2.10 (m, 2H), 1.82-1.68 (m, 3H), 1.45-1.25 (m, 2H). MS: m/z 391 (M+H)+.
