Reaction Steps
To a solution of 5,6-bis(p-anisyl)-2,3-dihydroimidazo[2,1-b]thiazole in 3 parts methylene chloride and 1 part absolute ethanol is added a solution containing an equimolar amount of sulfuric acid dissolved in absolute ethanol. The mixture is stripped of solvent and the residue recrystallized from absolute ethanol-ether containing a small amount of added sulfuric acid to give 5,6-bis(p-anisyl)-2,3-dihydroimidazo[2,1-b]thiazole sulfate, m.p. 268°-273° C. (dec.).
