Procedure
5-(2-Chloroethoxy)-3,3-dimethyl-2,3-dihydroindol-2-one (182 mg, 3.0 mmol) and N--(2-quinolylmethyl)piperazine (690 mg, 3.0 mmol) were mixed, followed by stirring at 150° C. for 3 hours under an argon gas stream. The resulting mixture was allowed to cool down, and was then dissolved in chloroform. The thus-obtained solution was washed with water and then dried over anhydrous sodium sulfate. After the solution was concentrated under reduced pressure, the residue was purified by chromatography on a silica gel column while using chloroform-methanol (10:1) as an eluent. Fractions containing the target compound were collected and then concentrated under reduced pressure. The concentrate was crystallized from n-hexane and was then recrystallized from ethyl acetate-ethyl ether, whereby 240 mg of the title compound were obtained as pale yellow powder (yield: 73%).
