Procedure

A mixture of 2-chloro-6-((R)-3-methylmorpholin-4-yl)-9H-purine (635 mg, 2.50 mmol), methyl iodide (187 μL, 3.00 mmol) and K2CO3 (484 mg, 3.50 mmol) in THF (15 mL) were stirred at r.t. for 18 h before further methyl iodide (187 μL, 3.00 mmol) was added. The resulting mixture was allowed to stir for 65 h then concentrated in vacuo. The resulting residue was partitioned between EtOAc and H2O, the organic phase washed with brine, then dried (Na2SO4) and concentrated in vacuo affording the title compound as an off-white solid (552 mg, 83%). LCMS (method H): RT 2.76 min [M+H]+ 268.3
