Water → (E)-N-[4-(3-hydroxypiperidinomethyl)phenyl]-3-(4-methylphenyl)cinnamamide

Participants

Reaction Steps

In DMF (3 ml) was dissolved (E)-N-[4—(chloromethyl)phenyl]-3—(4-methylphenyl)cinnamamide (200 mg), and to the mixture was added 3-hydroxypiperidine (168 mg). The mixture was stirred at room temperature for 13 hours, and to the mixture was added water (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 recrystallized from ethyl acetate-diisopropylether to give (E)-N-[4—(3-hydroxypiperidino-methyl)phenyl]-3—(4-methylphenyl)cinnamamide (Compound 67) (174 mg) as colorless crystals.
