Versuchsvorschrift
3-Methyl-1-phenylpyrazolin-5-one (1.51 g,)) was mixed with 3.5 g (0.0087 mol) 5-chloro-2-methylthio-3-methylbenzothiazolium tosylate in 25 ml methanol. Triethylamine (0.89 g,) was added. The mixture was stirred for 1.5 hours, then filtered and washed with methanol. After drying the yield was 2.75 g (89%), mp 206° C., λmax=379 (ε=26,000).
