Procedure

A 50-mL round-bottom flask was charged with a solution of tert-butyl N-(4-[[(3R)-3-[(2R)-2-hydroxypropyl]-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 (170 mg, 0.38 mmol, 1.0 equiv) in 5.5 mL of dichloromethane cooled to 0° C. Then hydrochloric acid (12 M, 0.5 mL) was added and the resulting solution was stirred for 3 h at room temperature. The reaction mixture was concentrated under reduced pressure to give (2R)-1-[(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]propan-2-ol hydrochloride (130 mg, crude) as a light yellow oil. The resulting hydrochloride (130 mg, crude) was dissolved in DMF (5 mL). Potassium carbonate (359 mg) and 2-chloro-1-(pyrrolidin-1-yl)ethan-1-one (125 mg) were added at room temperature and the resulting mixture was stirred for 14 h at 25° C. After completion of the reaction, the product was extracted with DCM, washed with brine and concentrated in vacuo. The crude product (160 mg) was purified by preparative HPLC under the following conditions (SHIMADZU): Column: SunFire Prep C18, 19*150 mm, 5 μm; mobile phase: water (with 0.1% HCOOH) and CH3CN (6.0% CH3CN up to 50.0% in 25 min); UV detection at 254/220 nm. The product containing fractions were collected and evaporated to remove the water and CH3CN to give 2-[(4-[[(3R)-3-[(2R)-2-hydroxypropyl]-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yl]oxy]cyclohexyl)(methyl)amino]-1-(pyrrolidin-1-yl)ethan-1-one (52.7 mg) as a white solid. MS (ES): m/z 473 (M+H)+. 1H NMR (400 MHz, CD3OD): δ 8.46 (1H, s), 5.32-5.18 (1H, m), 3.94-3.92 (1H, m), 3.57 (2H, t), 3.45 (2H, t), 3.36 (3H, m), 3.08-3.10 (1H, m), 2.96-2.98 (1H, m), 2.67-2.62 (2H, m), 2.41-2.29 (6H, m), 2.070-1.97 (5H, m), 1.95-1.87 (2H, m), 1.64-1.52 (5H, m), 1.30 (3H, d).
