To a suspension of tert-butyl(3S)-3-[4-(2-aminopyrimidin-5-yl)-2-(methylsulfanyl)-5,6-dihydro-7H-pyrrolo[2,3-d]pyrimidin-7-yl]-3-methylpyrrolidine-1-carboxylate (352 mg, 0.794 mmol) in DCM (8 mL) was added m-chloroperoxybenzoic acid (254 mg, 1.03 mmol, 70% purity) in three portions over 1 min at 0° C. The reaction mixture was stirred at 0° C. for 30 min. Four drops of DMSO was added and the reaction mixture was stirred for 5 min. The reaction mixture was purified via HPLC reversed phase column (XBridge C18 30×250 mm, mobile phase: 0%-50% of water with 0.1% EtOAc to acetonitrile with 0.1% EtOAc over 30 min, flow rate 80 mL/min) to give the title compound (200 mg, 55%) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ 8.78 (s, 2 H), 7.18 (s, 2 H), 3.89-3.75 (m, 2 H), 3.73-3.62 (m, 3 H), 3.42-3.34 (m, 3 H), 2.82 (s, 3 H), 2.41 (br s, 1 H), 2.15-2.01 (m, 1 H), 1.41 (s, 9 H), 1.33 (s, 3 H). m/z (APCI+) for C21H29N7O3S 460.6 (M+H)+.
