Notes:
1. The reaction of dimethylformamide chloride with N-methylbenzothiazolone methide yields the hemicyanine 2-dimethylaminovinyl-3-methyl-benzothiazolium chloride. By alkaline hydrolysis of the hemicyanine, the vinylogous aldehyde is obtained. The hemicyanine forms the symmetric cyanine (Thiazole Purple) by reaction with a second molecule of the methide. The cyanine as well as the vinylogous aldehyde can also be obtained directly from the amide chloride by reaction with the methide.
