Adding a certain compound to certain chemical reactions, such as: 722549-98-6, 4-Morpholinopyridin-2-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, name: 4-Morpholinopyridin-2-amine, blongs to pyridine-derivatives compound. name: 4-Morpholinopyridin-2-amine
General procedure: A solution of 2-bromo-1-(5-bromo-2,4-dimethoxyphenyl)ethanone 7 (124 rng, 0.367 mmol) and 4-(pyrrolidin-1-yl)pyridin-2-amine 8 (60 mg, 0.367 mmol) in acetone (4 mL) was heated at 75 C for 16 h. The reaction mixture was cooled to room temperature; the white precipitate was collected by filtration and solid was washed with acetone. The solid was suspended in aqueous ammonia solution (10 ml.) and stirred for 2 h. The free base was collected by filtration and solid was washed with water, dried under reduced pressure to yield 2-(5-bromo-2,4-dimethoxyphenyl)-7-(pyrrolidin-1-yl)imidazo[1,2-a]pyridine 9a (51 mg, 35%) as an off-white solid. 1H NMR (300 MHz, CDCl3): delta 8.55 (s, 1H), 7.83 (d, J = 7.4 Hz, 1H), 7,80 (s, 1H), 6.55 (s, 1H), 6,43 (d, J = 2.2 Hz, 1H), 6.33 (dd, J = 2,2, 7,4 Hz, 1H), 3 ,99 (s, 3H), 3 ,94 (s, 3H), 3.40-3,30 (m, 4H), 2.10-2.00 (m, 4H); HPLC (Method 2) >99% (AUC), tR= 19.12 min: APCI MS m/z 404 [M + H]+.
The synthetic route of 722549-98-6 has been constantly updated, and we look forward to future research findings.
