Reaction Steps

A mixture of (S)-2-amino-3-methyl-N-(2-phenylaminopyridin-3-yl)butyramide (3.0 mmol), 6-chloro-9-(tetrahydropyran-2-yl)-9H-purine (720 mg, 3.0 mmol) and DIPEA (2.6 mL, 15.0 mmol) in n-butanol (12 mL) was heated at 100° C. for 18 h in a sealed vial. 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, concentrated in vacuo and the resulting residue was purified by column chromatography (Si—PCC, gradient 0-10% 2M NH3/MeOH in DCM) to afford the title compound (821 mg, 68% over two steps). LCMS (Method J): RT 1.75 min [M+H]+ 403.2.
