실험 절차

Potassium carbonate (8.39 g) was dissolved in water (140 mL), followed by the addition of 7-(4-chlorobutoxy)-3,4-dihydrocarbostyril (19.4 g) and 1-(2,3-dichlorophenyl)piperazine monohydrochloride (16.2 g) thereto. The mixture was refluxed under stirring for about 3 hours. After reaction, the resulting mixture was cooled, and precipitated crystals were filtered. The crystals were dissolved in ethyl acetate (350 mL), and about 210 mL of water/ethyl acetate azeotrope was distilled under reflux. The remaining solution was cooled, and precipitated crystals were filtered. The thus-obtained crystals were dried at 60° C. for 14 hours, thereby obtaining 20.4 g of crude aripiprazole (yield: 74.2%).
