Reaction Steps

To 430 mg (2.0 mmol) of 2,4,6-trimethoxybenzoic acid, were added 10 ml of toluene, 0.52 ml (3.38 mmol) of triethylamine and 0.73 ml (3.40 mmol) of diphenylphosphoryl azide, and the mixture was stirred at 100° C. for one hour. After cooling the mixture to room temperature, 5 ml of a toluene solution containing 520 mg (2.2 mmol) of 2-(2,3-methylenedioxyphenyl)heptylamine was added and the mixture was stirred at room temperature over night. The reaction mixture was subjected to purification by silica-gel column chromatography and recrystallization from a mixed solvent of hexane and ethyl acetate to obtain 360 mg of 1-(2-(2,3-methylenedioxyphenyl)heptyl)-3-(2,4,6-trimethoxyphenyl)urea (Yield: 42.1%).
