Reaction Steps

A mixture of (1R,2R)-2-benzyloxy-1-(6-fluoro-1-phenyl-1H-benzoimidazol-2-yl)propylamine (100 mg, 0.27 mmol), 6-chloro-9-(tetrahydropyran-2-yl)-9H-purine (65 mg, 0.27 mmol) and DIPEA (240 μL, 1.35 mmol) in n-butanol (1 mL) was heated at 90° C. in a sealed vial for 18 h. After cooling to RT, the volatiles were removed in vacuo and the resulting residue loaded onto an Isolute® SCX-2 cartridge then washed with MeOH followed by 2M NH3/MeOH. The product containing fractions were combined and concentrated in vacuo. The resulting residue was purified by column chromatography (Si—PCC, gradient 0-10% 2M NH3/MeOH in DCM) to afford the title compound (128 mg, 96%). LCMS (Method J): RT 3.19 min [M+H]+ 494.1.
