Electric Literature of 16665-38-6 ,Some common heterocyclic compound, 16665-38-6, molecular formula is C7H9NO2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
4-Methoxypyridine-2-carbaldehyde, used as starting material was prepared as follows:- Manganese(IV) oxide (2.412 mL, 139.42 mmol, 4eq) was added portionwise to (4- methoxypyridin-2-yl)methanol (4.85g, 34.85 mmol, leq) in ethyl acetate (15OmL). The resulting mixture was stirred at 80 0C for 2 h. The hot reaction mixture was filtered through celite. The resulting mixture was evaporated to dryness to afford desired A- methoxypyridine-2-carbaldehyde (3.01 g, 21.93 mmol, 62.9 percent). IH NMR (400.132 MHz, DMSO) delta 3.93 (3H, s), 7.27 (IH, m), 7.44 (IH, d), 8.63 (IH, d), 9.96 (IH, s)
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,16665-38-6, its application will become more common.
