実験手順

A solution of 4-(4-fluorophenyl)-5-(4-pyridinyl)-1H-pyrazol-3-amine prepared as set forth in Example 2 (100 mg, 0.38 mmol), methyl isocyanate (22 mg, 0.39 mmol) and 4-dimethylaminopyridine (2.5 mg) in methylene chloride (10 ml) was stirred at room temperature for 30 minutes. The reaction was stripped in vacuo. The residue was triturated with hexane and the solid filtered to give pure N-[4-(4-fluorophenyl)-5-(4-pyridinyl)-1H-pyrazol-3-yl]-N'-methylurea, m. p. 212-213° C.
