Reaction Steps

To a suspension of sodium hydride (60% in mineral oil, 4.8 g, 120 mmol) in DMF (100 ml) was added dropwise at an ice bath temperature a solution of 2-formylpyrrole (9.5 g, 100 mmol) in DMF (10 ml). The mixture was stirred for 15 minutes at room temperature and cooled again. To the mixture was added dropwise a solution of benzylbromide (20.5 g, 120 mmol) in DMF (10 ml). The reaction mixture was stirred for 60 minutes at room temperature and poured to ice-water, and extracted with ethylacetate. The extract was washed with water and dried. The solvent was evaporated to give 1-benzyl-2-formylpyrrole (18.0 g) as an oil quantitatively.
