Application of 889865-45-6, 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.889865-45-6, name is 2,3-Dichloro-4-iodopyridine, molecular formula is C5H2Cl2IN, molecular weight is 273.89, as common compound, the synthetic route is as follows.
Compound N13z (135 mg, 318 mmol) in 1,4-dioxane (3 mL) was added Pd2(dba)3 (14.5 mg, 0.0159 mmol), XantPhos (18.4 mg, 0.0318 mmol), 2,3-dichloro-4-iodopyridine (109 mg, 0.397 mmol), and DIPEA (0.166 mL, 0.954 mmol). The reaction vessel was purged with argon, sealed, and heated to 110 C. until complete consumption of starting materials. The reaction mixture was cooled to room temperature, diluted with EtOAc and washed with water followed by brine. The organic partition was dried over magnesium sulfate, and filtered through Celite. The resulting solution was concentrated and purified by column chromatography (0-100% EtOAc in hexanes). This provided Compound E46a. LCMS ESI+ calc’d for C25H30Cl2N6O2S: 549.2 [M+H+]. found: 549.2 [M+H+].
Statistics shows that 889865-45-6 is playing an increasingly important role. we look forward to future research findings about 2,3-Dichloro-4-iodopyridine.
