Reaction Steps

A mixture of ethyl 5-ethyl-1-methyl-1H-pyrazole-3-carboxylate (5.03 g, 27.6 mmol) and ammonium hydroxide (28 mL of 30%) was stirred for 18 hours at ambient temperature. A precipitate formed, was isolated by filtration, and washed with cold hexanes to provide 2.60 g of 5-ethyl-1-methyl-1H-pyrazole-3-carboxamide as a white solid, mp 170-172° C.
