Methyl iodide → 6-Methoxy-1H-pyrrolo[2,3-b]pyridine

Participants

Reaction Steps

A mixture of 1H-pyrrolo[2,3-b]pyridin-6-ol (0.200 g, 1.49 mmol) and K2CO3 (1 g, 7.45 mmol) in acetone (30 mL) was stirred under N2 at room temperature for 1 h. MeI (0.166 g, 1.192 mmol) was added. The reaction mixture was stirred under N2 at 50° C. for 12 h and then filtered. The filtrate was concentrated to half its volume, diluted with water, and extracted with CH2Cl2. The organic layer was dried over anhydrous MgSO4, and evaporated to give a residue, which was purified on a column of silica gel eluting with EtOAc/hexane (1:4) to give 6-methoxy-1H-pyrrolo[2,3-b]pyridine (159 mg, 89%).
