2-Benzothiazolamine, 4-chloro- → Methyl 4-[4-chlorobenzothiazol-2-yl]allophanate

Participants

Reaction Steps

Five and one half parts by weight of methoxycarbonyl isocyanate was added gradually with stirring to a solution at room temperature of nine parts by weight of 2-amino-4-chlorobenzothiazole dissolved in 200 parts by weight of dioxane. After stirring the reaction mixture at room temperature overnight, a product was isolated by filtration giving a 45% yield of methyl 4-[4-chlorobenzothiazol-2-yl]allophanate having a melting point of 319°-20° C.
