Procedure

A mixture of ethyl 1-benzyl-5-methyl-1H-pyrazole-3-carboxylate (57.57 g, 0.236 mol), concentrated ammonium hydroxide (114 mL), and methanol (114 mL) was heated at 125° C. for 39 hours in a pressure vessel. After cooling to ambient temperature, the vessel was placed in an ice bath and the reaction solution was stirred for 30 minutes until a precipitate formed. The precipitate was isolated by filtration and washed with water to yield 28.22 g of 1-benzyl-5-methyl-1H-pyrazole-3-carboxamide.
