참여 물질

반응 단계

The thiourea is prepared by reacting 19.3 g. (0.1 mole) of 1-adamantyl isothiocyanate with 10 g. (0.1 mole) of cyclohexylamine in 250 ml. of ether at room temperature for 3 hrs. The thiourea which separates from solution is collected: 23.5 g., mp. 175-175.5. Evaporation of the ether filtrate to a small volume gives a second crop, 5.2 g., mp. 176-178. The combined yield is 28.7 g. (98.5 percent). A sample is recrystallized from alcohol and melts at 176°-177°.
