Procedure
A mixture of 3-amino-2-carbamoyl-4- {4-(3-methylphenylmethyl) phenyl} pyrazole (3.0 g), ethyl orthoformate (2 ml) and N,N-dimethylformamide (4 ml) was heated and stirred at 100° C. to 110° C. After 1 hour, to the mixture was added ethyl acetate (50 ml). The precipitate was separated by filtration, washed with etyl acetate, dried to give the title compound (2.0 g).
