실험 절차

3-Methyl-1-phenylpyrazolin-5-one (1.74 g, 0.01 mol) was mixed with 3.68 g (0.01 mol) 2-methylthio-3-methylbenzothiazolium tosylate in 25 ml methanol. Triethylamine (1.01 g, 0.01 mol) was added. The mixture was stirred for one hour, then filtered and washed with methanol. After drying the yield was 2.46 g (78%), mp 159°-162° C., λmax=375 (ε=25,000).
