Reaction Steps

A mixture of 3-cyclopropyl-5-fluoro-2-{(S)-1-[9-(tetrahydropyran-2-yl)-9H-purin-6-ylamino]ethyl}-3H-benzoimidazole-4-carboxylic acid (64 mg, 0.14 mmol), HATU (63 mg, 0.17 mmol), morpholine (18 μL, 0.216 mmol) and DIPEA (47 μL, 0.28 mmol) in DCM (2 mL) was stirred at RT for 1 h. The crude mixture was loaded onto an Isolute® SCX-2 cartridge which was washed with MeOH followed by 2M NH3/MeOH. The basic fractions were combined, concentrated in vacuo and the resulting residue purified by column chromatography (Si—PCC, gradient 0-10% MeOH in DCM) to afford 389 (46 mg, 75%) as a white solid. LCMS (Method K): RT 2.49 and 2.53 min [M+H]+ 451.05. 1H NMR (DMSO-d6, 400 MHz): δ 8.24-7.83 (3H, m), 7.69-7.60 (1H, m), 7.10 (1H, t, J=9.53 Hz), 6.07-5.84 (1H, m), 3.90-3.83 (1H, m), 3.80-3.72 (1H, m), 3.69-3.59 (2H, m), 3.59-3.50 (2H, m), 3.41-3.35 (2H, m), 3.28-3.20 (1H, m), 1.72-1.63 (3H, m), 1.26-0.85 (4H, m)
