Procedure

To a solution of 2-chloro-9-methyl-6-((R)-3-methylmorpholin-4-yl)-9H-purine (550 mg, 2.05 mmol) in THF (20 mL) at −78° C. was added LiHMDS (3.1 mL, 3.08 mmol, 1M solution in THF). The resulting mixture was allowed to stir for 45 min before the addition of DMF (800 μL, 10.33 mmol). The reaction mixture was warmed to r.t. over 1.5 h then poured onto 0.5M HCl. The resulting precipitate was collected by filtration and washed with H2O then Et2O affording the title compound as a yellow solid (406 mg, 67%). LCMS (method H): RT 3.35 min [M+H]+ 296.3
