Reaction Steps

A mixture of 4-{1-[2-chloro-6-morpholin-4-yl-9-(tetrahydropyran-2-yl)-9H-purin-8-ylmethyl]azetidin-3-yl}piperazin-2-one (990 mg, 2.00 mmol), 2-ethylbenzimidazole (322 mg, 2.20 mmol), tris(dibenzylideneacetone)dipalladium (46 mg, 0.05 mmol), XPhos (95 mg, 0.20 mmol) and Cs2CO3 (980 mg, 3.01 mmol) in dioxane (30 mL) was purged with argon then heated at 115° C. for 6 h then stirred at r.t. for 16 h. The reaction mixture was filtered through Celite®, washing with dioxane, and the filtrate concentrated in vacuo. The resulting residue was purified by column chromatography (Si—PCC, MeOH:DCM, 0-10%) affording the title compound (470 mg, 39%). LCMS (method A): RT 2.01 and 1.92 min [M+H]+ 601.6
