Related Products of 84249-14-9, Adding some certain compound to certain chemical reactions, such as: 84249-14-9, name is 2-Amino-4-bromopyridine,molecular formula is C5H5BrN2, 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 84249-14-9.
To a stirred solution of 2-amino-4-bromopyridine (1.0 g, 5.78 mmol) in 1,4-dioxane (2 ml) was added K3PO4 (2.45 g, 11.56 mmol) and l,r-bis(di-tert-butylphosphino)ferrocene (0.168 g, 0.29 mmol) at rt. The reaction was purged with nitrogen for 30 min before adding phenylboronic acid (1.05 g, 8.67 mmol) and Pd(OAc)2 (0.065 g, 0.29 mmol) at rt. The reaction mixture was heated at 80C for 16 h. The resulting reaction mixture was cooled to rt, poured into water (50 ml) and extracted with EtOAc (3 x 25 ml). The combined organic phase was washed with water (25 ml). The organic phase was separated, dried over Na2S04, filtered and concentrated under reduced pressure. The crude material was purified by flash chromatography (62% EtOAc in hexane) yielding 4-phenylpyridin-2-amine (0.42 g, 2.47 mmol). LCMS: Method C, 1.47 min, MS: ES+ 171.14; NMR (400 MHz, DMSO-d6) delta ppm 7.96 (d, J=5.2 Hz, 1 H), 7.63 – 7.65 (m, 2 H), 7.41 – 7.52 (m, 3 H), 6.77 (dd, J=1.6 Hz, 5.2 Hz, 1 H), 6.69 (d, J=1.2 Hz, 1 H), 6.00 (s, 2 H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 84249-14-9, 2-Amino-4-bromopyridine, other downstream synthetic routes, hurry up and to see.
