実験手順

A solution of 10 g of aniline in 50 ml of pyridine is cooled to 0° C. and a solution of 14.56 g of diethylcarbamoyl chloride in 10 ml of pyridine is added slowly. The mixture is stirred for 6 hours, the temperature being allowed to rise to RT, and is then poured into water. It is extracted with AcOEt, washed with water and with a 5% solution of potassium hydrogensulfate, dried over sodium sulfate and evaporated under vacuum. The residue is chromatographed on silica using DCM and then a DCM/AcOEt mixture (90/10; v/v) as the eluent to give 13 g of the expected product, which is used as such in the next step.
