Water → (E)-N-[4-[3-(hydroxymethyl)piperidinomethyl]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 solution were added 3—(hydroxymethyl)piperidine (191 mg). The mixture was starred at room temperature for 72 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—(hydroxy-methyl)piperidinomethyl]phenyl]-3—(4-methylphenyl)cinnamamide (Compound 66) (160 mg) as colorless crystals.
