Versuchsvorschrift
1,1-Dimethyl-3-(5-tert.-butyl-3-isoxazolyl)urea is prepared by condensing dimethylamine with 5-tert.-butyl-3-isoxazolyl isocyanate in benzene. After removal of the reaction solvent and purification by chromatography or crystallization, there is obtained 1,1-dimethyl-3-(5-tert.-butyl-3-isoxazolyl)urea. M.P. 119.5°-120.5° C.
