Related Products of 19798-80-2, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 19798-80-2, name is 4-Chloropyridin-2-amine, molecular formula is C5H5ClN2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
5.2.2.30 7,8-Dichloro-1,4-dihydropyrido[2,3-b]pyrazine-2,3-dione (30) To a solution of 2-amino-4-chloropyridine (1.28 g, 10.0 mmol) in DMF (40 mL) at -20 C was added NCS (2.67 g, 20.0 mmol). This mixture was allowed to warm to room temperature and stirred for 24 h, and then poured into 300 mL ice-water and extracted with ethyl acetate. The extracts were washed with 1 M NaOH and brine, dried and evaporated. The residue was purified by column chromatography on silica gel to give 4,5-dichloropyridin-2-amine (1.12 g, 69.0%).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 19798-80-2, 4-Chloropyridin-2-amine.
