참여 물질

반응 단계

29.2 g N-(2-cyanoethyl)-aniline is dissolved in 200 ml acetonitrile and then reacted with 23.97 g chloroformic acid-[3-(cyclopropylcarbonylamino)-phenyl]-ester with stirring, with which the temperature of the solution rises to about 35° C. After standing overnight the solvent is removed under vacuum, The remaining oily residue is treated with water, the water is decanted and the oil brought to crystallization with a 1:1 mixture of isopropyl ether/isopropanol. The crystallizate is finally recrystallized from isopropanol.
