Procedure
To a solution of 4-[[(12S)-12-[2-[(tert-butyldimethylsilyl)oxy]ethyl]-8-thia-4,6-diazatricyclo[7.4.0.0[2,7]]trideca-1(9),2(7),3,5-tetraen-3-yl]oxy]-N,N-dimethylcyclohexan-1-amine (110 mg, 0.22 mmol, 1.00 equiv) in methanol (5 mL) was added hydrochloric acid (12 M, 0.5 mL) at 0° C. The resulting solution was stirred for 1 h at room temperature. The solvent was removed in vacuo and the crude product (80 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 53.0% in 16 min); flow rate: 20 mL/min; UV detection at 254/220 nm. The product-containing fractions were collected and partially evaporated under reduced pressure to remove water and CH3CN. The residue was lyophilized overnight to give the 2-[(12S)-3-[[4-(dimethylamino)cyclohexyl]oxy]-8-thia-4,6-diazatricyclo[7.4.0.0[2,7]]trideca-1(9),2(7),3,5-tetraen-12-yl]ethan-1-ol formate (46 mg, 55%) as an off-white semi-solid. MS (ES): m/z 376 (M+H)+. 1H NMR (300 MHz, CDCl3): δ 8.49 (d, 2H), 5.22 (s, 1H), 3.82 (t, 2H), 3.16 (m, 2H), 2.88 (s, 2H), 2.66 (s, 6H), 2.48 (t, 3H), 2.19 (s, 2H), 2.05 (d, 2H), 1.70 (m, 7H).
