Reaction Steps
A mixture of 3 parts of 2,3-dihydroimidazo[2,1-b]benzothiazol-7-amine, 15 parts of 2-bromo-2-methylpropane and 13.5 parts of N,N-dimethylformamide is stirred for 20 hours at 80° C. The reaction mixture is poured onto 50 parts of water. The precipitated product is filtered off, washed successively with water, 2-propanol and 2,2'-oxybispropane, and dried, yielding 3 parts of N-(2,3-dihydroimidazo[2,1-b]benzothiazol-7-yl)formamide monohydrobromide; mp. 287.3° C.
