Benzene, 1-(chloromethyl)-2-fluoro- → HCID 59490939, compound

Participants

Reaction Steps

3-(2-Methoxy-pyridin-3-yl)-5-methyl-1H-pyrrolo[3,2-b]pyridine-2-carboxylic acid ethyl ester B3 (0.2 g, 0.64 mmol) was diluted with DMF (4 mL). To the resulting solution was added 2-fluorobenzyl chloride (0.14 g, 0.96 mmol) and cesium carbonate (0.312 g, 0.96 mmol) and the resulting suspension was allowed to stir at room temperature. After 24 hours the reaction mixture was then diluted with ethyl acetate (50 mL) and water (20 mL) and the layers were separated. The organic layer was sequentially washed with aqueous saturated sodium bicarbonate solution (10 mL), water (10 mL) and saturated brine (10 mL), dried (magnesium sulfate), filtered and concentrated in vacuo. The crude residue obtained was purified using flash chromatography to provide 1-(2-Fluoro-benzyl)-3-(2-methoxy-pyridin-3-yl)-5-methyl-1H-pyrrolo[3,2-b]pyridine-2-carboxylic acid ethyl ester B4 (0.26 g) MS: 420.20 (M+H)+.
