Synthetic Route of 2897-43-0 ,Some common heterocyclic compound, 2897-43-0, molecular formula is C5H3Cl2N3O2, 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.
To a solution of 2,6-dichloro-3-nitro-pyridin-4-amine (2.6 g, 14.4 mmol) from Step A in MeOH (150 mL) was added Raney Nickel catalyst (2 g) and the reaction agitated under a hydrogen atmosphere in a Parr apparatus (35 p.s.i.) for 2 h . The reaction mixture was filtered through a pad of Celite and concentrated to yield the title compound. MS: m/z = 179 (M + 1).
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. 2897-43-0, 2,6-Dichloro-3-nitropyridin-4-amine, other downstream synthetic routes, hurry up and to see.
