Reference of 66909-38-4, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.66909-38-4, name is 6-Chloro-4-methylpyridin-3-amine, molecular formula is C6H7ClN2, molecular weight is 142.5862, as common compound, the synthetic route is as follows.
A mixture OF 4-(6-CHLORO-5-METHYL-PYRIMIDIN-4-YLOXY)-PIPERIDINE-1-CARBOXYLIC acid isopropyl ester (1.80 g, 5.74 mmol), palladium acetate (155 mg, 0.69 mmol), biphenyl-3-yl-di-tert-butyl- phosphane (21.5 mg, 0.072 mmol), sodium tert-butoxide (1.38 g, 14.4 mmol), and 6-CHLORO-4-METHYL- pyridin-3-ylamine (838 mg, 5.80 mmol) in 20 mL dioxane was heated in microwave for 1 hour at 120C. Solids were filtered off and mixture was purified by column chromatography (hexane/AcOEt) to give Compound A98 as a tanned solid (702 mg, 29%). H NMR (CDCL3, 400 MHz) 8 1.24-1. 26 (d, 6H), 1.72-1. 81 (M, 2H), 1.95-2. 02 (M, 2H), 2.10 (s, 3H), 2.27 (s, 3H), 3.37-3. 43 (M, 2H), 3.74-3. 77 (M, 2H), 4.90-4. 97 (m, 1H), 5.29-5. 34 (M, 1H), 5.91 (s, 1H), 7.00 (s, 1H), 8.22 (s, 1H), 8.57 (s, 1H). Exact mass calculated for C2OH26CIN503 419.17, found 420.4 (MH+).
The chemical industry reduces the impact on the environment during synthesis 66909-38-4, I believe this compound will play a more active role in future production and life.
