Procedure

A solution of 3.8 g of α-ethyl-4-(1H-imidazol-1-yl)-α-methyl-β-oxobenzenepropanoic acid methyl ester, 2.0 g of hydrazine hydrate and 25 ml of ethanol was refluxed for 20 hours. The ethanol is removed and the residue is treated with ether and water. Filtration of the solid gives after recrystallization from ethyl acetate, 2.7 g of a crystalline solid, mp 86°-88° C.
