반응 단계

2,2-Dimethyl-4-hydroxy-1,3-benzodioxole (14 parts) in benzene (25 parts) was treated with methyl isocyanate (6 parts) and a few drops of triethylamine with cooling. After standing for 30 minutes, the crystals of 2,2-dimethyl-1,3-benzodioxol-4-yl N-methylcarbamate which formed were filtered off and washed with benzene then with petroleum (boiling point below 40° C.) to yield the pure compound as a white solid, melting point 129°-130° C. (16 parts, 85% yield).
