Procedure

A mixture of (R)-1-(6-fluoro-1-pyridin-2-yl-1H-benzoimidazol-2-yl)-2-methoxyethylamine (69 mg, 0.24 mmol), 6-chloro-9-(tetrahydropyran-2-yl)-9H-purine (56 mg, 0.24 mmol) and DIPEA (0.21 mL, 1.2 mmol) in IPA (1 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 was purified by column chromatography (Si—PCC, gradient 0-7.5% 2M NH3/MeOH in DCM) to afford 270 as a white solid (48 mg, 49%). LCMS (Method K): RT 3.07 min [M+H]+ 405.0. 1H NMR (DMSO-d6, 400 MHz): δ 12.80 (1H, br s), 8.65 (1H, s), 8.16-8.04 (2H, m), 7.98 (1H, s), 7.87-7.81 (1H, m), 7.79 (1H, d, J=8.01 Hz), 7.72 (1H, dd, J=8.82, 4.90 Hz), 7.56-7.49 (1H, m), 7.21-7.10 (2H, m), 6.05 (1H, s), 3.90 (2H, d, J=6.25 Hz), 3.20 (3H, s)
