Reaction Steps

5 g (51.87 mmol) 3-Amino-5-methyl-1,2,4-triazole, 16.2 g (67.4 mmol) diethyl (3-fluorophenyl)malonate and 20.4 mL tributylamine are stirred at 180° C. over night. The mixture is diluted with 2N NaOH solution and water and extracted three times with methyl-tert. butylether. These organic extracts are discarded. The aqueous phase is acidified at 0° C. with concentrated HCl until pH 3. The white precipitate is collected by filtration, washed with water (4 L) and dried in vacuo at 50° C. 11.97 g (88.7%) of the product are obtained and are used without further purification.
