Procedure

A mixture consisting of 6.7 g of 1-(p-chlorobenzyl)-3-ethoxycarbonyl-5-n-butoxypyrazole, 30 ml of a 28% aqueous ammonia solution and 30 ml of methanol was placed in an autoclave and heated at a temperature of 60°C for 2 hours. After completion of the reaction, the solvent was removed by distillation and the residue was recrystallized from methanol-petroleum ether to give 5.3 g (86.2% yield) of 1-(p-chlorobenzyl)-3-carbamoyl-5-n-butoxypyrazole as colorless needles having a melting point of 137° - 138°C.
