実験手順

A mixture of (R)-2-benzyloxy-1-(6-fluoro-1-phenyl-1H-benzoimidazol-2-yl)ethylamine (298 mg, 0.83 mmol), 6-chloro-9-(tetrahydropyran-2-yl)-9H-purine (200 mg, 0.83 mmol) and DIPEA (700 μL, 4.2 mmol) in n-butanol (5 mL) was heated at 90° C. in a sealed vial for 48 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 as a colourless oil (256 mg, 64%). LCMS (Method B): RT 3.26 min [M+H]+ 480.2.
