Reaction Steps

To a mixture of 41 mg of copper iodide, 1.82 g of tripotassium phosphate, 38 mg of N,N′-dimethylethylenediamine, 1.00 g of 1-(4-iodophenyl)methyl amine, and 510 mg of 2-piperidone was added 4.29 mL of toluene, followed by stirring at 80° C. overnight under an argon atmosphere. The reaction liquid was filtered through Celite, the filtrate was then concentrated under reduced pressure, and the obtained residue was purified by silica gel column chromatography (chloroform:methanol=10:1) to obtain 552 mg of 1-[4-(aminomethyl)phenyl]piperidine-2-one.
