実験手順

To a solution (5 ml) of 1.25 g (10 mmol) of methyl pyrrole-2-carboxylate in benzene was added 2.71 g (11 mmol) of tetradecanoyl chloride under ice-cooling, followed by adding 1.73 ml (15 mmol) of stannic chloride dropwise thereto. The mixture was stirred for 2 hours at room temperature, treated with diluted hydrochloric acid and extracted with ethyl acetate. The extract was washed with water and dried over anhydrous magnesium sulfate. After removing the solvent under reduced pressure, the product was purified by subjecting it to column chromatography over silica gel (ethyl acetate/hexane=1/7) to obtain 1.80 g (54% yield) of methyl 4-tetradecanoylpyrrole-2-carboxylate.
