Procedure

To a solution of methyl 1H-pyrrolo[3,2-b]pyridin-6-carboxylate (50 mg) in N-methyl-2-pyrrolidone (1 mL) were added potassium carbonate (158 mg) and 2,6-dimethylbenzyl chloride (91 mg), and then the reaction mixture was subjected to microwave irradiation at 160° C. for 30 minutes. The reaction mixture was quenched with water, and extracted with ethyl acetate. The obtained organic layer was dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography to give the titled compound (21 mg) as a white solid.
