Reference of 943323-65-7 , The common heterocyclic compound, 943323-65-7, name is 4-Bromo-1H-pyrrolo[2,3-b]pyridin-3-amine, molecular formula is C7H6BrN3, 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 solution of 4-bromo-1 H-pyrrolo[2,3-b]pyridin-3-amine (220 mg, 1.04 mmol)[prepared according to Example 89], 3-furoic acid (128 mg, 1.14 mmol) and diisopropylethyl amine (595 mul_, 3.42 mmol) in DCM (10 mL) at 25 C was added PyBrop (580 mg, 1.25 mmol) in one portion. After 12h, the solution was partitioned between H2O/DCM. The aqueous phase was washed several times with DCM and the combined organic fractions were dried over Na2SO4, concentrated and purified using column chromatography (silica, 3% MeOH in DCM) affording the title compound (290 mg, 91%) as an orange oil: LC-MS (ES) m/z = 307 (M+H)+.

The synthetic route of 943323-65-7 has been constantly updated, and we look forward to future research findings.

Reference of 943323-65-7, Adding some certain compound to certain chemical reactions, such as: 943323-65-7, name is 4-Bromo-1H-pyrrolo[2,3-b]pyridin-3-amine,molecular formula is C7H6BrN3, 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 943323-65-7.

To a solution of 4-bromo-1 H-pyrrolo[2,3-b]pyridin-3-amine (63 mg, 0.298 mmol) in dioxane (2.5 mL) and H2O (0.5 ml_) was added 1 ,1-dimethylethyl [3- phenyi-2-({[5-(4,4,5,5-tetramethyl-1 ,3,2-dioxaborolan-2-yl)-2- thienyl]carbonyl}amino)propyl]carbamate (145 mg, 0.298 mmol)[prepared inExample 87], Pd(PPh3)4 (17 mg, 14.9 mumol) and K2CO3 (164 mg, 1.19 mmol). After heating to 800C for 12h in a sealed tube, the reaction solution was partitioned between H2CVDCM. The aqueous phase was washed several times with DCM and the combined organic fractions were dried over Na2SO4, concentrated and purified using column chromatography (silica, 3% MeOH in DCM) affording the title compound (60 mg, 41 %) as an orange oil: LC-MS (ES) m/z = 492 (M+H)+.

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. 943323-65-7, 4-Bromo-1H-pyrrolo[2,3-b]pyridin-3-amine, other downstream synthetic routes, hurry up and to see.
