Reaction Steps

A mixture of (S)-1-(5-methyl-1-phenyl-1H-benzoimidazol-2-yl)ethylamine from Example 14 (100 mg, 0.398 mmol), 6-chloro-9H-purine (74 mg, 0.478 mmol) and DIPEA (0.347 mL, 1.99 mmol) in n-butanol (2 mL) was stirred in a sealed vial for 20 h at 120° C. After cooling to RT, volatiles were removed under reduced pressure and the resulting residue was purified by column chromatography (Si—PCC, gradient 0-20% MeOH in EtOAc) and then triturated with acetonitrile affording 117 as an off-white solid (54 mg, 37%). LCMS: RT 3.11 min [M+H]+ 370.1. 1H NMR (DMSO, 400 MHz): δ 12.90 (1H, bs), 8.20-8.00 (2H, m), 7.84 (1H, s), 7.69-7.39 (6H, m), 7.07-6.89 (2H, m), 5.49 (1H, bs), 2.39 (3H, s), 1.53 (3H, d, J=6.79 Hz)
