New learning discoveries about 4,6-Dichloro-2-phenylpyrimidine

The synthetic route of 3740-92-9 has been constantly updated, and we look forward to future research findings.

Adding a certain compound to certain chemical reactions, such as: 3740-92-9, 4,6-Dichloro-2-phenylpyrimidine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, name: 4,6-Dichloro-2-phenylpyrimidine, blongs to pyrimidines compound. name: 4,6-Dichloro-2-phenylpyrimidine

EXAMPLE 6 This Example illustrates the preparation of (E)-methyl 2-[2-(6-chloro-2-phenylpyrimidin-4-yloxy)phenyl]-3-methoxypropenoate (Compound No.378 of Table II). A stirred solution containing (E)-methyl 2-(2-hydroxyphenyl)-3-methoxypropenoate (208mg) and 4,6-dichloro-2-phenylpyrimidine (225mg, prepared according to the method of D. B. Harden, M. J. Mokrose and L. Strekowski, J.Org.Chem, 1988, 53, 4137-4140) in DMF (5 ml) was cooled to 0° C. Potassium carbonate (138mg) was then added and stirring was continued at 0° C. under an atmosphere of nitrogen. After 3 hours, the temperature was allowed to rise to room temperature and stirring was continued overnight. The reaction mixture was diluted with water and then acidified with dilute hydrochloric acid. The resulting mixture was extracted with ether (*3) and the combined ether extracts were washed successively with dilute aqueous sodium hydroxide solution (*2) and water (*3) and then dried. Evaporation of the solvent gave an oil (0.31 g), which solidified on standing. Chromatography (eluent ether-hexane, 1:2) afforded the title compound (0.12 g, 30percent) as an off-white solid; m.p. 118-120° C.; 1H NMR: delta 3.54(3H,s), 3.67(3H,s), 6.65(1H,s), 7.22-7.50(7H,m), 7.44(1H,s), 8.28-8.33(2H,m) ppm; IR maxima: 1708, 1631 cm-1.

The synthetic route of 3740-92-9 has been constantly updated, and we look forward to future research findings.
