Reaction Steps
A mixture of 5.5 parts of imidazo[2,1-b]benzothiazol-6-amine and 7.5 parts of diethyl 2-(ethoxymethylene)propanedioate is stirred for 30 minutes at 110° C. The solid product is suspended in 1,1'-oxybisethane. It is filtered off and dried, yielding 10 parts (95%) of diethyl 2-[(2,3-dihydroimidazo[2,1-b]benzothiazol-6-yl)aminomethylene]propanedioate; mp. 140° C.
