By a procedure substantially similar to that of Example 14, 8 g (0.023 mol) of ethyl 4,5-bis(4-fluorophenyl)-1H-pyrazole-1-acetate of Example 3 and 34.3 mL (0.22 mol) of diethylaminopropylamine were reacted to produce 4.45 g of N-[3-(diethylamino)propyl]-4,5-bis(4-fluorophenyl)-1H-pyrazole-1-acetamide. The solid product after trituration in water collapsed to a non-crystalline, white, waxy solid upon drying.
