Versuchsvorschrift
With 300 mg of 5-chloro-3-(2-methoxyphenyl)-3-[2-oxo-2-(4-pyridin-4-yl piperazin-1-yl)ethyl]-1,3-dihydro-2H-indol-2-one, which is the compound described in Example 1A of the brochure Publication No. WO03/008407, and 201 mg of 4-methoxy-2-(trifluoromethoxy)benzene sulfonyl chloride as starting materials, 382 mg of a free form of the title compound (pale yellow amorphous) was obtained by a similar method to Example 2. To a solution of 360 mg of the obtained free form in CHCl3 (10 ml) was added a solution of 4 mol/L hydrochloric acid/EtOAc (0.62 ml), and the reaction mixture was stirred at room temperature for 3 hours. Thereafter, the solvent was evaporated under reduced pressure, IPA (5 ml) was added to the obtained residue, then the mixture stirred for 30 minutes while heating at 90° C. external temperature, then, the mixture was stirred at room temperature for 62 hours. The precipitated solid was collected by filtration to obtain 375 mg of the title compound (colorless solid).
