Reaction Steps
3-Methyl-1-phenylpyrazolin-5-one (1.74 g, 0.01) was mixed with 4.3 g (0.01 mol) 5-chloro-2-ethylthio-3-ethylbenzothiazolium tosylate in 15 ml methanol. Triethylamine (1.01 g, 0.01 mol) was added. The mixture was stirred for 1 hour, then filtered and washed with methanol. After drying the yield was 2.20 g (59%), mp 161°-162.5° C., λmax=382 (ε=21,000).
