実験手順
Aniline (19 g) was dissolved in 400 ml of toluene, and with stirring and cooling, a solution of 30 g of N-4-chlorobenzyl-N-2-norbornylcarbamoyl chloride in 50 ml of toluene was added dropwise. After the addition, the temperature of the mixture was gradually raised, and it was stirred for about 10 hours at about 70° to 80° C. After cooling, the precipitated aniline hydrochloride was separated by filtration. The toluene layer was washed successively with water, a 1% aqueous solution of sodium carbonate, 1% hydrochloric acid and then water, and then dried over anhydrous sodium sulfate. Toluene was evaporated, and the residue was recrystallized from a mixture of hexane and ethanol to give 23 g of the desired 1-(4-chlorobenzyl)-1-(2-norbornyl)-3-phenylurea. mp. 111°-113° C.
