These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,3435-28-7, its application will become more common.

Adding a certain compound to certain chemical reactions, such as: 3435-28-7, 6-Methylpyrimidin-4-amine, 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, 3435-28-7, blongs to pyrimidines compound. Application In Synthesis of 6-Methylpyrimidin-4-amine

A mixture of 2-(4-bromo-7-fluorothiazolo[5,4-c]pyridin-2-yl)-3-chlorobenzonitrile (0.110 g, 0.30 mmol), 6- methylpyrimidin-4-ylamine (35 mg, 0.32 mmol), XantPhos (0.018 g, 0.03 mmol) and Cs2C03 (247 mg, 0.75 mmol) in dioxane (2.5 mL) was degassed with a stream of argon. Pd2(dba)3 (0.014 g, 0.015 mmol) was added and the reaction mixture was heated at 80 C for 2 hours in a sealed vial. After cooling to room temperature, the crude reaction mixture was filtered through Celite washing with EtOAc (50 mL). The filtrate was concentrated to dryness under reduced pressure. The resultant residue was purified by column chromatography on silica gel eluting with 0-100% EtOAc in DCM, then triturated with diethyl ether (x 2), to afford the title compound as a pale yellow solid (43 mg, 36% yield). NMR (400 MHz, CDC13): delta 8.73 (d, J = 1.2 Hz, 1H), 8.34 (d, J = 1.8 Hz, 1H), 7.86-7.76 (m, 3H), 7.66 (t, J = 8.0 Hz, 1H), 7.57 (br s, 1H), 2.56 (s, 3H). LCMS (Method C): RT = 3.31 min, m/z: 397 [M+H+].

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,3435-28-7, its application will become more common.
