Reaction Steps

A mixture of (S)-1-(6-fluoro-7-methyl-1-phenyl-1H-benzoimidazol-2-yl)ethylamine dihydrochloride (330 mg, 1.23 mmol), 6-chloro-9-(tetrahydropyran-2-yl)-9H-purine (351 mg, 1.47 mmol) and DIPEA (320 μL, 2.45 mmol) in n-butanol (6 mL) was heated at 90° C. in a sealed vial for 18 h. After cooling to RT, the volatiles were removed under reduced pressure and the resulting residue purified by column chromatography (Si—PCC, gradient 0-10% MeOH in EtOAc). A solution of the compound thus obtained in MeOH (5 mL) and 4N HCl in dioxane (1 ml) was stirred at RT for 1 h then the volatiles were removed under reduced pressure. The resulting residue was partitioned between EtOAc and a saturated solution of NaHCO3. A white solid precipitated and was collected by filtration to afford 183 (333 mg, 70%). LCMS (Method K): RT 3.46 min [M+H]+ 388.1. 1H NMR (DMSO-d6, 400 MHz): δ 12.55 (1H, s), 8.06-8.00 (2H, m), 7.71-7.39 (7H, m), 7.05 (1H, dd, J=10.58, 8.77 Hz), 5.30 (1H, br s), 1.70 (3H, d, J=1.84 Hz), 1.53 (3H, d, J=6.84 Hz)
