1-piperazin-1-ylhexan-1-one

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 4-(benzyloxy)-2-(chloromethyl)-3-methylquinoline (200 mg), 1-hexanoylpiperazin (130 mg), potassium carbonate (111 mg), and DMF (6 mL) was stirred at room temperature for 2 hours. Water (30 mL) was added to the reaction mixture, followed by extraction with ethyl acetate (50 mL). The organic layer was washed sequentially with water and saturated brine, and then dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and then the residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate=1/1) to obtain 4-(benzyloxy)-2-[(4-hexanoylpiperazin-1-yl)methyl]-3-methylquinoline (241 mg). followed by extraction with ethyl acetate (50 mL) The organic layer was washed sequentially with water and saturated brine dried over anhydrous magnesium sulfate The solvent was evaporated under reduced pressure the residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate=1/1)
