Versuchsvorschrift

2 g (0.01 mol) of 2,3,5,6-tetrahydro-6-phenylimidazo-[2,1-b]-thiazole and 2.8 g (0.01 mol) of decyl ester of monobromacetic acid are dissolved in 25 ml of acetone and allowed to stand overnight at room temperature. The product is filtered-off and washed with acetone to give 4.6 g (96%). After crystallization from dioxane there are obtained 3.6 g (75%) of 2,3,5,6-tetrahydro-6-phenyl-7-decyloxycarbonylmethylimidazo-[2,1-b]-thiazolium bromide, m.p. 127°-128° C.
