Reaction Steps

A mixture of (S)-1-(5-fluoro-1-phenyl-1H-benzoimidazol-2-yl)ethylamine from Example 29 (379 mg, 1.4 mmol), 6-chloro-9-(tetrahydropyran-2-yl)-9H-purine (340 mg, 1.4 mmol) and DIPEA (1.2 mL, 7.0 mmol) in n-butanol (7 mL) was stirred in a sealed vial for 18 h at 90° C. After cooling to RT, volatiles were removed under reduced pressure and the resulting residue 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 161 (65 mg, 12%). LCMS: RT 3.34 min [M+H]+ 374.1. 1H NMR (DMSO, 400 MHz): δ 8.19-8.00 (2H, m), 7.92 (1H, s), 7.67-7.41 (6H, m), 7.06 (2H, d, J=7.13 Hz), 5.47 (1H, s), 1.56 (3H, d, J=6.83 Hz)
