Reaction Steps

A suspension of 4-chloro-5-methyl-5H-pyrrolo[3,2-d]pyrimidine (28) (300 mg, 1.79 mmol), 4-nitro-2-fluorophenol (422 mg, 2.69 mmol) and cesium carbonate (1.2 g, 3.58 mmol) in diphenyl ether (18 mL) was stirred overnight at 140° C. The reaction mixture was cooled to room temperature, concentrated under reduced pressure and the residue was triturated with Et2O, filtered, and dried to afford the title compound 29 as a grey solid (258 mg, 49% yield). LRMS (M+1) 289.1 (100%).
