실험 절차

20.6 g (0.1 mole) of 3-cyano-4-tert.-butyl-thien-2-yl isocyanate were added dropwise to a solution of 6.5 g (0.145 mole) of dimethylamine in 200 ml of toluene at room temperature. After the exothermic reaction had subsided, the mixture was concentrated and the residue was recrystallized from a little toluene. 20.1 g of 1-(3-cyano-4-tert.-butyl-thien-2-yl)-3,3-dimethyl-urea of melting point 140° C. were obtained in this manner.
