Introduction of a new synthetic route about 1256805-54-5

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. 1256805-54-5, 6-Chloro-4-methoxypyridin-3-amine, other downstream synthetic routes, hurry up and to see.

Electric Literature of 1256805-54-5, Adding some certain compound to certain chemical reactions, such as: 1256805-54-5, name is 6-Chloro-4-methoxypyridin-3-amine,molecular formula is C6H7ClN2O, 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 1256805-54-5.

To a mixture of 6-chloro-4-methoxypyridin-3-amine (0.50 g, 3.1 mmol) andpotassium isothiocyanate (0.61 g, 6.3 mmol) in acetic acid (5 mL) at room temperature wasadded bromine (0.18 mL, 3.4 mmol) in acetic acid (2 mL) over 30 mm. The mixture wasstirred at room temperature for 16 h before additional potassium isothiocyanate (0.61 g, 6.3 mmol) and acetic acid (1 mL) were added. The mixture was stirred at room temperature for 24 h. To the mixture was added water (100 mL) and the mixture was stirred for 2 h. The insoluble material was collected by suction filtration and the filter cake was suspended in water (100 mL) and stirred for 2 h. The solid was collected by suction filtration and driedunder vacuum at 50 C to give 5-chloro-7-methoxythiazolo[5,4-bjpyridin-2-amine (0.70 g,3.1 mmol, 100% yield) as atan solid. MS (ESI)m/z: 215.9 [M+Hf 1H NMR (500 MI-Tz, DMSO-d6) oe 7.74 (br s, 2H), 7.02 (s, 1H), 3.94 (s, 3H).

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. 1256805-54-5, 6-Chloro-4-methoxypyridin-3-amine, other downstream synthetic routes, hurry up and to see.
