Procedure

A solution of potassium hydroxide (1.1 g, 19.5 mmol) in water (30 mL) and ethanol (30 mL) is added to a slurry of hydroxylamine hydrochloride (2.7 g, 39 mmol) in ethanol (50 mL). 5-(2,5-dimethyl-pyrrol-1-yl)-2-methyl-2H-pyrazole-3-carboxylic acid dimethylamide (1.6 g, 6.5 mmol) is added and the mixture is refluxed for 48 hours. The contents of the flask are then concentrated under reduced pressure and the residue is suspended in DCM. The suspension is heated to reflux and then cooled down to room temperature, filtered and the filtrate is concentrated to give crude product. MS (ESI) m/z 169.3 (M+1).
