Reaction Steps

A 183 mg portion of 2-methyl-6-propyl-7-[[2'-(N-triphenylmethyl-tetrazol-5-yl)biphenyl-4-yl]methyl]-1H-pyrazolo[1,5-b][1,2,4]triazole (compound 1c) was treated in the same manner as described in Example 12, the resulting residue was dissolved in ethyl acetate with heating and then the solution was cooled to collect the thus formed precipitate by filtration, thereby giving 85 mg of 2-methyl-6-propyl-7-[[2'-(tetrazol-5-yl)biphenyl-4-yl]methyl]-1 H-pyrazolo[1,5-b][1,2,4]triazole in the form of colorless amorphous solid.
