Versuchsvorschrift
A solution of 2-methylbenzothiazole (5.0 g, 0.033 mol) and benzyl bromide (40 mL, 0.33 mol) in 250 mL of ethyl acetate was refluxed under nitrogen for 48 hours. Solid had formed. The mixture was filtered and washed with cold ethyl acetate to give 3-benzyl-2-methylbenzothiazol-3-ium bromide as a light yellow solid, mp 230-231° C.
