A solution of N-methyl-p-carbmethoxybenzamide in chloroform was treated with phosphorus pentachloride to give E. Then E was reacted with p-carbmethoxybenzoyl hydrazine to yield dimethyl-4,4'-(4-methyl-1,2,4-triazol-3,5-diyl)dibenzoate, (F). Then III was obtained by reacting F in a similar manner as in Example 1.
