PROCEDURE

实验过程

A mixed solvent of ethanol (10 ml) and water (10 ml) containing N-{3-cyano-4-[4-(5-methylisoxazol-4-ylcarbonyl) piperazin-1-yl]phenyl}-1-(4-fluorophenyl)-5-methylpyrazole-4-carboxamide (0.95 g) and sodium hydroxide (0.1 g) was stirred at a refluxing temperature for 2 h. The solvent was evaporated under reduced pressure. Dilute hydrochloric acid was added to the residue to allow crystallization. The crystals were recrystallized from hydrous dimethylformamide to give the title compound (0.45 g), melting point: 210° C.
