1-Methylpiperazine → HCID 18472616, compound

Participants

Reaction Steps

In THF (7 ml) was dissolved N-[4—(chloromethyl)-phenyl]-7—(4-methylphenyl)-3,4-dihydro-naphthalene-2-carboxamide (150 mg), and to the mixture was added 1-methylpiperazine (129 μl). The mixture was refluxed for 24 hours. The reaction mixture was cooled to room temperature, and to the mixture was added 5% sodium hydrogen carbonate solution (50 ml). The mixture was extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride solution, dried with anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was separated and purified with column chromatography (ethyl acetate/triethylamine=20/1) and recrystallized from ethyl acetate-hexane to give 7—(4-methylphenyl)-N-[4—(4-methyl-1-piperazinylmethyl)phenyl]-3,4-dihydronaphthalene-2-carboxamide (Compound 40) (105 mg) as colorless crystals.
