Procedure

Tert-butyl 4-(4-((R)-3-methylmorpholino)-6-(1-(S-methylsulfonimidoyl)cyclopropyl)pyrimidin-2-yl)-1H-pyrrolo[2,3-c]pyridine-1-carboxylate (0.223 g, 0.44 mmol) was added to TFA (5 ml) and DCM (5.00 ml). The resulting solution was stirred at RT for 1 hour. The reaction mixture was evaporated and the residue was purified by preparative HPLC using decreasingly polar mixtures of water (containing 1% NH3) and MeCN as eluents. Fractions containing the desired compound were evaporated and the residue was triturated with Et2O to give a solid which was collected by filtration and dried under vacuum to afford the title compound (0.086 g, 48%); 1H NMR (400 MHz, DMSO-d6) 1.29 (3H, d), 1.40-1.60 (3H, m), 1.76 (1H, d), 3.11 (3H, s), 3.12-3.21 (1H, m), 3.53 (1H, t), 3.68 (1H, d), 3.80 (2H, d), 4.01 (1H, d), 4.20 (1H, s), 4.58 (1H, s), 6.95 (1H, d), 7.28 (1H, s), 7.71 (1H, s), 8.83 (1H, s), 9.08 (1H, s), 11.75 (1H, s); m/z: (ES+) MH+, 413.16.
