Electric Literature of 1256785-40-6, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 1256785-40-6, name is Methyl 4-amino-6-chloronicotinate. This compound has unique chemical properties. The synthetic route is as follows.

Step 1: Methyl 4-amino-6-chloronicotinate (15 g, 80 mmol) obtained by the method described in US2012/184562 and sodium hydroxide (13 g, 322 mmol) were stirred in a mixed solution of methanol (100 mL) and water (50 mL) at room temperature for 12 hours. The reaction mixture was adjusted to pH 6 with a 6.0 mol/L aqueous hydrochloric acid solution, and the resulting solid was collected by filtration, whereby 4-amino-6-chloronicotinic acid (8.0 g, yield: 58%) was obtained. 1H-NMR (300 MHz, DMSO-d6, delta): 8.47 (s, 1H), 7.52 (br s, 2H), 6.75 (s, 1H)

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 1256785-40-6, Methyl 4-amino-6-chloronicotinate.

Application of 1256785-40-6 ,Some common heterocyclic compound, 1256785-40-6, molecular formula is C7H7ClN2O2, 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 stirred suspension of LiAlH4 (1.0 g, 26.3 mmol) in dry THF (500 mL) at 0 C. under nitrogen was added dropwise a solution of 4-amino-6-chloro-nicotinic acid methyl ester (2.6 g, 13.9 mmol) (from Example 22 supra) in THF (100 mL). After the addition, the reaction mixture was stirred at this temperature for 1 hour. The reaction was quenched slowly with water (1.5 mL) and filtered. The organic solution was evaporated to give (4-amino-6-chloro-pyridin-3-yl)-methanol as a white solid which was used directly in the next step. (Yield 2.2 g, 100%). LC-MS: [M+H]+ 159.0.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1256785-40-6, its application will become more common.
