2-Methyltetrahydrofuran → 7-(4-(4-(2,3-Dichlorophenyl)piperazin-1-yl)butoxy)-3,4-dihydroquinolin-2-yl dibenzylcarbamate

Participants

Reaction Steps

A mixture of aripiprazole (1.5 g, 3.3 mmol), dibenzylcarbamoyl chloride (1.74 g, 6.7 mmol) silver carbonate (3.75 g, 13.4 mmol) and 2-methyltetrahydrofuran (30 mL) was heated at reflux for 4 days. The reaction mixture was cooled, diluted with ethyl acetate and water, and then filtered through celite. The organic phase was separated, dried over MgSO4 and evaporated. The residue obtained was further purified on silica eluting with ethyl acetate/tetrahydrofuran to give after evaporation of the major product containing fractions, Compound-80 (1.02 g) was a yellow oil.
