Reaction Steps

To a solution of tert-butyl {1-[(3S)-3-{4-(2-aminopyrimidin-5-yl)-2[(3S)-3-methylmorpholin-4-yl]-5,6-dihydro-7H-pyrrolo[2,3-d]pyrimidin-7-yl}-3-methylpyrrolidin-1-yl]-2-methyl-1-oxopropan-2-yl}carbamate (778 mg, 0.1 mmol) in MeOH (6.5 mL) was added 4 N HCl in dioxane (6.7 mL, 26.8 mmol) dropwise at 0° C. and the reaction was stirred at room temperature for 2 h. Toluene was added and the mixture was concentrated to give a residue that was purified by SFC/ZymorSpher HAP column (150×21.2 mm) eluting with 15-35% CO2 in MeOH over 6 min at 120 bar and with a flow of 100 mL/min to give 468 mg of the title compound as a white solid. The solid was treated with hydroxide resin in MeOH for 15 min or until pH˜8 was reached. The resin was removed by filtration washing with MeOH and 7 N ammonia in MeOH several times. The filtrate was concentrated under reduced pressure, dried under high vacuum and lyophilized to give the title compound (387.8 mg, 60%) as a white solid. 1H NMR (400 MHz, DMSO-d6, 80° C.) δ 8.73 (s, 2 H), 6.60 (br s, 2 H), 4.63 (d, J=6.6 Hz, 1 H), 4.36-4.16 (m, 2 H), 4.00 (d, J=11.6 Hz, 1 H), 3.94-3.85 (m, 1 H), 3.75-3.37 (m, 7 H), 3.22-3.05 (m, 3 H), 2.44-2.29 (m, 1 H), 2.08-1.95 (m, 1 H), 1.69 (br s, 2 H), 1.32 (s, 3 H), 1.28 (s, 6 H), 1.22 (d, J=6.72 Hz, 3 H). m/z (APCI+) for C24H35N9O2 482.6 (M+H)+.
