Reaction Steps

A mixture of (S)-1-(6-fluoro-1-phenyl-1H-benzoimidazol-2-yl)propylamine from Example 28 (42 mg, 0.16 mmol), 6-chloro-9-(tetrahydropyran-2-yl)-9H-purine (37 mg, 0.16 mmol) and DIPEA (0.14 mL, 0.8 mmol) in n-butanol (1 mL) was stirred in a sealed vial for 16 h at 90° C. After cooling to RT, the crude reaction mixture was loaded into an Isolute® SCX-2 which was washed with MeOH followed by 2M NH3/MeOH. The basic fractions were combined and concentrated in vacuo. The resulting residue was purified by column chromatography (Si—PCC, gradient 0-10% 2M NH3/MeOH in DCM) affording 160 as a white solid (13 mg, 21%). LCMS: RT 3.61 min [M+H]+ 388.1. 1H NMR (DMSO, 400 MHz): δ 8.22-8.03 (2H, m), 7.80 (1H, s), 7.71-7.43 (6H, m), 7.09 (1H, t, J=9.42 Hz), 6.85 (1H, d, J=8.93 Hz), 5.38 (1H, s), 2.08-1.88 (2H, m), 0.83 (3H, t, J=7.34 Hz)
