YieldReaction ConditionsOperation in experiment
93.1% for 16 h; Reflux Dissolve 7.0 g (28.4 mmol) of 4,4-difluoro-1-(3-fluoro-4-methoxyphenyl)-1,3-butanedione in 150 ml of ethanol and add 7.4 g (33 mmol) of 4 The sulfonamide phenylhydrazine hydrochloride was stirred under reflux for 16 hours. The reaction solution was allowed to cool, and water was added until the crystal slowly precipitated. The product was dried by suction and dried to give a pale yellow product. Yield 87percent.
87% for 16 h; Heating / reflux 4,4-Difluoro-1-(3-fluoro-4-methoxyphenyl)-butane-1,3-dione from Step 2 (7.0 g, 28.4 mmol) was dissolved in ethanol (150 mL). To the stirred mixture was added 4-sulphonamidophenyl hydrazine hydrochloride (7.4 g, 33 mmol) and stirred at reflux overnight (16 hours). The mixture was cooled and water was added until crystals slowly appeared. The product was isolated by filtration and air dried to provide the desired product as a light tan solid (9.8 g, 87percent): mp 159-161 °C. Anal. Calc'd. for C17H14N3SO3F3: C, 51.38; H, 3.55; N, 10.57. Found: C, 51.46; H, 3.52; N, 10.63.
