실험 절차

0.16 g (1.0 mmol) of (4-chlorobenzyl)-methylamine was dissolved in 30 ml of pyridine, and 0.3 g (1.0 mmol) of N-methyl-N-(2-methyl-1-(4-trifluoromethyl-pyrimidin-5-yl)-propyl]-carbamoyl chloride was dropwise added, followed by stirring at room temperature for 10 hours. To the reaction solution, 50 ml of water was added, followed by extraction with diethyl ether. The obtained organic phase was washed twice with 30 ml of a dilute citric acid aqueous solution, followed by drying over anhydrous magnesium sulfate. Diethyl ether was distilled off under reduced pressure, and the obtained crude product was purified by silica gel chromatography (developing solvent/n-hexane:ethyl acetate=8:1 to 3:1) to obtain 0.22 g (yield: 52%) of 1-(4-chlorobenzyl)-1,3-dimethyl-3-[2-methyl-1-(4-trifluoromethyl-pyrimidin-5-yl)-propyl]-urea as colorless crystals (melting point: 95-98° C.).
