Procedure

A solution of 5 g of 3-methyl-6-hydroxymethyl-imidazo-(2,1-b)thiazole in 100 ml of dry chloroform is dropped at 35° into a solution of 15 ml of butyroyl chloride and 12 ml of pyridine in 75 ml of dry chloroform. The suspension obtained is stirred for 1 hour at room temperature and then filtered. The filtrate is concentrated by evaporation. The residue obtained is dissolved in abs.ethanol and a stream of dry hydrochloric acid is bubbled into the solution to yield 4.5 g of 3-methyl-6-butyroxymethyl-imidazo-(2,1-b)thiazole hydrochloride; m.p. 126°-128°.
