Adding a certain compound to certain chemical reactions, such as: 1018450-37-7, name is 4-Chloro-3-fluoro-2-iodoaniline, belongs to iodides-buliding-blocks compound, 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 1018450-37-7, Formula: C6H4ClFIN
To a solution of 4-chloro-3-fluoro-2- iodoaniline (300 mg, 1.105 mmol) in EtOAc (6.9 mL) was added to a solution of HCl (37% wt, 2.3 mL, 27.8 mmol) in water (6.9 mL) at 0C. The resulting mixture was stirred for 10 minutes. To this suspension was added a solution of sodium nitrite (84 mg, 1.216 mmol) in water (0.5 mL) over three minutes. The reaction was stirred for 30 min. A solution of sodium azide (79 mg, 1.216 mmol) in 0.5 mL water was added slowly to the above reaction mixture. The mixture was then stirred in an ice-water bath under nitrogen and allowed to warm to rt overnight. The mixture was extracted with ethyl acetate (2 x 30 mL). The combined organic fractions were washed with brine (30 mL) and dried over sodium sulfate, filtered and the solvent was evaporated under reduced pressure to give the title compound.
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, 4-Chloro-3-fluoro-2-iodoaniline, other downstream synthetic routes, hurry up and to see.
