Reaction Steps

The mixture of ethyl 3-aminobenzoate (2.0 g), hexane-2,5-dione (1.8 ml) and acetic acid (0.7 ml) in benzene (10.0 ml) was heated under reflux for 5 hours, while water was removed in a Dean-Stark apparatus. To the mixture was added a mixture of ethyl acetate and water and the mixture was adjusted to pH 8 with potassium carbonate. The separated organic layer was washed with a brine, dried over magnesium sulfate and evaporated in vacuo to give ethyl 3-(2,5-dimethylpyrrol-1-yl)benzoate (2.9 g) as an oil.
