Procedure

A mixture of (S)-1-(6-fluoro-1-pyridin-2-yl-1H-benzoimidazol-2-yl)ethylamine (764 mg, 3.0 mmol), 6-chloro-9-(tetrahydropyran-2-yl)-9H-purine (710 mg, 3.0 mmol) and DIPEA (2.6 mL, 15 mmol) in IPA (8 mL) was heated for 16 h at 90° C. After cooling to RT, the volatiles were removed under reduced pressure and the resulting residue loaded onto an Isolute® SCX-2 cartridge. The cartridge was washed with MeOH followed by 2M NH3/MeOH. The basic fractions were combined, concentrated in vacuo and the resulting residue purified by column chromatography (Si—PCC, gradient 0-10% 2M NH3/MeOH in EtOAc) to afford 210 as a white solid (700 mg, 63%). LCMS (Method K): RT 2.94 min [M+H]+ 375.0. 1H NMR (DMSO-d6, 400 MHz): δ 12.89 (1H, br s), 8.61 (1H, br s), 8.20-7.80 (4H, m), 7.79-7.67 (2H, m), 7.52-7.43 (1H, m), 7.20-7.08 (2H, m), 5.86 (1H, br s), 1.63 (3H, d, J=6.82 Hz)
