Reaction Steps
A solution of 10.7 g (0.035 mol) of ethyl 4,5-diphenylpyrazole-1-acetate of example 1 in 10.9 g (0.094 mol) of 2-[(1,1-dimethylethyl)amino]ethanamine was heated with about 50 mg of sodium methoxide at about 150° for two hours. The excess amine was stripped off under vacuum and the residue was triturated in acetonitrile. The solid product was filtered off and recrystallized from isopropyl acetate to yield 8.8 g of white crystals, mp 115°-116° C.
