実験手順

To a mixture of 1-benzenesulfonyl-5-chloromethyl-1H-pyrrolo[2,3-b]pyridine (3.3 g, 10.76 mmol) in methanol (15 mL) was added sodium methoxide (1.74 g, 32.3 mmol) at room temperature and the resulting mixture was stirred for 12 h. The mixture was diluted with ethyl acetate (250 mL), washed with brine, dried over anhydrous sodium sulfate and then concentrated in vacuo to afford 5-methoxymethyl-1H-pyrrolo[2,3-b]pyridine (1.74 g, quant.) as a light yellow solid which was used in the next step without further purification: LC/MS m/e calcd for C9H10N2O [M+H]+ 163.19, observed 162.9.
