实验步骤: Many of the novel ureas and thioureas of this invention are prepared by reacting arylisocyanates and arylisothiocyanates with secondary amines. These reactions may be performed in aprotic solvents such as hexane, diethyl ether, toluene, tetrahydrofuran, and the like at temperatures from room temperature or below up to the boiling point of the solvent used. The ureas and thioureas are isolated by filtration or by evaporation of the solvent, and they may be purified by recrystallization, absorption chromatography, or distillation under reduced pressure Examples of this process are the reaction of 2,4-dimethylphenylisocyanate with N-benzyl-N-(n-butyl)amine to yield 1-benzyl-1-(n-butyl)-3-(2,4-dimethylphenyl)urea and the reaction of 6-[[(4-butylphenyl)methyl]amino]-1-hexanol with 2,4-dimethylphenyl isocyanate in hexane at room temperature to yield 1-[(4-butylphenyl)methyl]-3-(2,4-dimethylphenyl)-1-(6-hydroxyhexyl)urea.

实验步骤: A stirred solution of 6.0 g of N-benzyl-n-butylamine in 3 ml of methylene chloride containing 4.5 ml of triethylamine, under inert gas, was cooled to 0° C. and treated by the dropwise addition of 4.27 ml of iso-valerylchloride. Another 3 ml of methylene chloride was added and stirred at ambient temperature for 18 hours. The insolubles were filtered and the cake washed with methylene chloride. The combined filtrates were washed with water, brine and dried. Evaporation of the volatiles gave a brown oil which was purified by chromatography on silica gel using 1:8 ethyl acetate:-hexanes giving 7.75 g of the desired product as a yellowish oil. The insolubles were filtered the cake washed with methylene chloride The combined filtrates were washed with water, brine dried Evaporation of the volatiles gave a brown oil which was purified by chromatography on silica gel using 1:8 ethyl acetate
