2-Chloro-4-methyl-3-nitropyridine Use and Manufacturing
Synthesis of the compound 10 The compound 9 (13g, 0.084mol) was added into 50mL of phosphorus oxychloride, the mixture was heated under reflux for 4 h, and distilled to remove excessive phosphorus oxychloride. The resulted product was recrystallized in 50mL of ethanol (75percent) to yield 11 g of a white solid product with yield of 75.3percent. The melting point: 51.7-52.1 °C(ethanol) (M.P. 52.0-52.9 °C was reported in reference)[J.O.C., 1955, 20, 1729-1731].
A cyclopropyldipyridodiazepinone derivative for use as non-nucleoside reverse transcriptase inhibitors.
