Versuchsvorschrift
In an 8 ml acetic acid solution of 1.07 g of 3-amino-4-(4phenylthiophenyl)pyrazole, 0.6 ml of ethyl 4,4,4-trifluoroacetoacetate was added and stirred for 2 hours at 100° C. After allowing to cool, ether was added, and the precipitate was filtered and dried, and the title compound was obtained (200 mg, 13%).
