実験手順
A mixture of 2.4 g of 6-chloro-1'-methylspiro[indoline-3,4'-piperidine], 0.5 g of sodium hydride and 6 g of 2-fluorobenzotrifluoride in 30 ml of dimethylsulfoxide is stirred under nitrogen for 30 minutes. An exothermic reaction occurs during this time. Thereafter, the mixture is diluted with water, and the diluted mixture thrice with ether. The combined ether extracts are extracted with 2N hydrochloric acid. The acidic extracts are basified providing a colorless oil. The oil is dissolved in ether and the solution is dried. The product is passed through an alumina column, ether eluant, to provide a colorless oil which is converted, in ether, to its maleic acid salt. The salt is recrystallized from an acetone-ether mixture to provide white platelets, mp 209°-211° C. of 6-chloro-1-(2-trifluoromethylphenyl)-1'-methylspiro[indoline-3,4'-piperidine] maleate.
