9/15/21 News Analyzing the synthesis route of 889939-26-8

The synthetic route of 889939-26-8 has been constantly updated, and we look forward to future research findings.

In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 889939-26-8, name is 4-Bromo-2-iodo-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine, the common compound, a new synthetic route is introduced below. HPLC of Formula: C13H8BrIN2O2S

A sealed tube containing a suspension of 5-(2~iodo-1-(phenylsulfonyl)- 1 H-pyrrolo[2,3-b]pyridn-4-yl)-2-((tetrahydrQ-2H-pyran-4-yl)oxy)benzonitrile (100 mg, 0.171 mmol) and Pd(PPh?)4 (9 mg, 0.008 mmol) in a degassed mixture of dioxane/H20 (1.5mL, 4/1 ), was preheated at 85 C for 5 rnin. Next, K2C03 (59 mg, 0.43 mmol) and 2- (3,6-dhydro-2H-pyran-4-yl)-4,4,5,5-tetramethyl-1 ,3,2-dioxaborolane (54 mg, 0.257 mmol), were added to the mixture and the reaction was additionally heated at 100 C in the sealed tube for 15 hrs. Afterwards, the crude material was allowed to reach room temperature. It was concentrated to dryness; the residue was triturated with EtOH and filtered through a short pad of Celite, washing the solids with CH2CI2. The filtrate was concentrated to dryness. The residue was purified by flash column chromatography on silica gel to afford 5-(2-(3,6-dihydro-2H-pyran-4-yl)-1- (phenylsulfonyl)-l H-pyrroio [2,3-b]pyridin-4-yl)-2-((tetrahydro-2H-pyran-4- yl)oxy)benzonitrile. LCMS-ESI+ (m/z): [M+H]+ calcd for C30H27N3O5S: 542.2; found: 542.2
