Aripiprazole

A mixture of 7-(4-Bromobutoxy)-2(1H)-quinolinone (297 g, 1.0 mol), NaI (234 g, 1.56 mol),
triethylamine (173.7 g, 1.72 mol) and 1-(2, 3-dichlorophenyl)-piperazine hydrochloride (381
g, 1.43 mol), in acetonitrile (750 mL) was refluxed for 4 h with stirring. Progress of reaction
was monitored by TLC; using benzene: ethyl acetate (7:3) solvent system. The reaction
mixture was filtered, and the filtrate was evaporated to dryness in vacuo. The residue was
extracted with CHCl3, and the extract was washed, dried, and evaporated in vacuo.
Recrystallization from MeOH-CHCl3 gave the desired product as colorless needles. Product
Yield: 407.0 g, 84 %
