Reaction Steps

A mixture of (S)-1-(4-fluoro-1-phenyl-1H-benzoimidazol-2-yl)ethylamine from Example 15 (0.407 mmol), 6-chloro-9-(tetrahydropyran-2-yl)-9H-purine (122 mg, 0.509 mmol) and DIPEA (0.444 mL, 2.55 mmol) in n-butanol (3 mL) was stirred in a sealed vial for 20 h at 100° C. After cooling to RT, volatiles were removed under reduced pressure and the resulting residue was purified by column chromatography (Si—PCC, gradient 0-10% MeOH in EtOAc). The product containing fractions were concentrated in vacuo and the resulting residue was dissolved in EtOAc (10 mL) and stirred with 2N HCl (10 mL) for 15 min. Volatiles were removed under reduced pressure and the residue was dissolved in MeOH (2 mL) and triturated with diethyl ether affording 136 as a beige powder (126 mg, 78%). LCMS: RT 3.47 min [M+H]+ 374.0. 1H NMR (DMSO, 400 MHz): δ 10.03 (1H, s), 8.66 (1H, s), 8.55 (1H, s), 7.68-7.38 (5H, m), 7.28-7.21 (1H, m), 7.13 (1H, dd, J=10.91, 7.98 Hz), 6.94 (1H, dd, J=8.11, 0.82 Hz), 5.68-5.59 (1H, m), 1.72 (3H, d, J=6.85 Hz)
