Reaction Steps

A mixture of (S)-3-benzyloxy-1-(6-fluoro-1-phenyl-1H-benzoimidazol-2-yl)propylamine (639 mg, 1.7 mmol), 6-chloro-9-(tetrahydropyran-2-yl)-9H-purine (410 mg, 1.7 mmol) and DIPEA (1.5 mL, 8.5 mmol) in n-butanol (6 mL) was heated at 100° C. for 18 h. After cooling to RT, the volatiles were removed in vacuo 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 and concentrated in vacuo and the resulting residue purified by column chromatography (Si—PCC, gradient 0-10% 2M NH3/MeOH in DCM) to afford the title compound as a white solid (703 mg, 84%). LCMS (Method C): RT 3.10 min [M+H]+ 494.3.
