Procedure

A mixture of (2,6-dichloro-pyridin-3-yl)-(1H-pyrrol-2-yl)-methanone (1.8 g) and hydrazine hydrate (0.5 mL) in ethanol (70 mL) was heated at 90° C. for 20 hours. The reaction was concentrated to 40 mL, diluted with water (5 mL) and cooled. The precipitate was collected and dried to give 0.84 g of the titled compound.
