Reference of 5305-59-9, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 5305-59-9, name is 6-Chloropyrimidin-4-amine. This compound has unique chemical properties. The synthetic route is as follows.
A mixture of 6-chloropyrimidin-4-amine (0.324 g, 2.5 mmol), phenylboronic acid (0.381 g, 3.13 mmol), Na2CO3 (0.795 g, 7.50 mmol) and Bis(triphenylphosphine)palladium(II) chloride (0.035 g, 0.050 mmol) were suspended in a mixture of Dioxane (15 mL)/EtOH (2 mL)/water (3 mL). The mixture was heated a heating block at 125 C for 2 h and concentrated. The residue was purified on the silica gel using 100 % ethyl acetate, then 10% methanol in ethyl acetate. The desired fractions were concentrated to give an off-white solid (0.25 g, 58 %).1H NMR (400 MHz, DMSO-d6) d ppm 8.44 (1 H, d, J=1.26 Hz), 7.93 – 8.00 (2 H, m), 7.42 – 7.52 (3 H, m), 6.91 (2 H, s), 6.88 (1 H, d, J=1.26 Hz). LCMS (method D) tR, 2.58min., MH+ = 172.1.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 5305-59-9, 6-Chloropyrimidin-4-amine.
