Reference of 623942-84-7, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.623942-84-7, name is (3-Bromo-6-methoxypyridin-2-yl)methanol, molecular formula is C7H8BrNO2, molecular weight is 218.05, as common compound, the synthetic route is as follows.

(3-bromo-6-methoxypyridin-2-yl)methanol (2.5 g, 11.4 mmol) and CBr4 (4.5 g, 13.6 mmol) were added into DCM (30 mL). PPh3 (3.6 g, 13.6 mmol) in DCM (10 mL) was added dropwise into the reaction mixture at 0 C. The mixture was stirred at 0 C for 0.5 hour. The reaction was concentrated to give a residue. The residue was purified by flash silica gel chromatography (40 g column, EtOAc in petroleum ether from 0% to 10%) to afford 3- bromo-2-(bromomethyl)-6-methoxypyridine (2.69 g, 84% yield) as a colorless oil. LCMS m/z [M+H]+ = 281.8.

Statistics shows that 623942-84-7 is playing an increasingly important role. we look forward to future research findings about (3-Bromo-6-methoxypyridin-2-yl)methanol.

Synthetic Route of 623942-84-7 ,Some common heterocyclic compound, 623942-84-7, molecular formula is C7H8BrNO2, 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 mixture of (3-bromo-6-methoxypyridin-2-yl)methanol (1.9 g, 8.7 mmol) in dichloromethane (100 mL) was added N-bromosuccinimide (1.8 g, 10 mmol) and triphenylphosphine (2.6 g, 10 mmol) under an ice bath condition and nitrogen atmosphere. The reaction mixture was stirred at rt for 3 h and then concentrated in vacuo, the residue was purified by column chromatography on a silica gel eluted with PE/EA (v/v = 30/1) to give the title compound as light yellow liquid (1.4 g, 57 %).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,623942-84-7, its application will become more common.
