Reaction Steps

2 g (0.01 mol) of 2,3,5,6-tetrahydro-6-phenylimidazo-[2,1-b]-thiazole are dissolved in 20 ml of acetone and added with 1.53 g (0.01 mol) of methyl ester of monobromacetic acid. After 12 hours the residue is filtered-off and washed with acetone to give 2.86 g (81%) of 2,3,5,6-tetrahydro-6-phenyl-7-methoxycarbonylmethylimidazo-[2,1-b]-thiazolium bromide melting at 81°-82° C.
