실험 절차

A solution of 3.4 g of 6-chloro-1'-cyano-1-(2-fluorophenyl)spiro[indoline-3,4'-piperidine], Example 26, in 50 ml of tetrahydrofuran is added dropwise to a refluxing slurry of 1.0 g of lithium aluminum hydride in 50 ml of tetrahydrofuran. After total addition the mixture is stirred at reflux for 2.5 hours before being treated with water and alkali. The resulting oily product, in ether, is converted to its maleic acid salt which is recrystallized from an ethyl alcohol-ether mixture to provide off-white granules, mp 174.5°-175.5° C. of 6-chloro-1-(2-fluorophenyl)spiro[indoline-3,4'-piperidine] meleate.
