2,4,5-Trichloropyrimidine Use and Manufacturing
5-Chlorouracil (4.5 g, 30.82 mmol) was dissolved in phosphorus oxychloride (100 mL) and phosphorus pentachloride (19.2 g, 92.46 mmol) was added. The reaction mixture was heated at reflux overnight; it was then cooled to RT and the solvent was evaporated under reduced pressure. The residue was cooled to 0 compound 1 Example 10 N-(2-(2, 5 -dichloropyrimidin-4-ylamino)phenyl)-cyclopropanecarboxamide; A 500 mL round bottomed flask was charged with 5-chlorouracil a (25.0 g, 170 mmol, 1.0 equiv) and phosphoryl chloride (159 mL, 1.7 mol, 10 equiv). The reaction vessel was equipped with a vigoreaux column followed by careful addition of diisopropylethylamine (59 mL, 340 mmol, 2.0 equiv) over 1 minute. Evolution of white fumes was observed during the addition of diisopropylethylamine. The reaction was then heated to 110 Method 19 Method 3 Method 5 Method 8 Method 11 3A Preparation of 2, 4, 5-trichloropyrimidine
