Reaction Steps

N-(1-Methylpyrrol-2-yl)acetamide (3.20 g, 0.0231 mol) in dry dimethylformamide was maintained at a temperature less than 0° C, with stirring under nitrogen, during the slow addition of 50% sodium hydride/oil (1.11 g, 0.0231 mol). After the addition, the mixture was stirred at 0° C. for 30 minutes and then the temperature allowed to rise to 15° C. when n-butyl iodide (8.50 g, 0.0461 mol) was added. The mixture was stirred at room temperature overnight and then poured into water (200 ml) and the mixture extracted with ether (4 × 50 ml). The combined extracts were washed with water (3 × 50 ml) and dried over magnesium sulphate. The solvent was removed in vacuo and the resulting oil distilled to give a colourless oil 3.72 g (83%) b.p. (airbath) 100° C/0.4 mm.
