With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.29608-05-7,4-(Piperidin-1-ylmethyl)aniline,as a common compound, the synthetic route is as follows.
WORKING EXAMPLE 71 (Production of Compound 71) In THF (10 ml) was dissolved 3-(2-methylphenyl)cinnamic acid (0.48 g), and to the solution were added oxalyl chloride (0.35 ml) and a drop of DMF. The mixture was stirred at room temperature for 1 hour and concentrated under reduced pressure. The residue was dissolved in THF (20 ml), and to the solution were added 1-(4-aminobenzyl)piperidine (0.38 g) and triethylamine (0.34 ml) at room temperature. The reaction mixture was stirred at room temperature for 2 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 magnesium sulfate and concentrated under reduced pressure. The residue was washed with ethyl acetate-diisopropylether to give (E)-N-[4-(piperidinomethyl)phenyl]-3-(2-methyl-phenyl)-cinnamamide (Compound 71) (0.75 g) as pale yellow amorphous.
