Reference of 1190862-70-4, Adding some certain compound to certain chemical reactions, such as: 1190862-70-4, name is Ethyl 5-bromo-6-methylnicotinate,molecular formula is C9H10BrNO2, 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 1190862-70-4.
17C: A mixture of 1A (250 mg, 0.605 mmol), bis(pinacolato)diboron (192 mg,0.756 mmol), potassium acetate (178 mg, 1.815 mmol) and PdC12(dppf)-CH2C12 adduct (24.70 mg, 0.030 mmol) in dioxane (6 mL) was heated at 100 C for 60 mm. After cooling to rt, ethyl 5-bromo-6-methylnicotinate (150 mg, 0.615 mmol) and1,1 ?-bis(di-tert-butylphosphino)ferrocenepalladium dichloride (20.03 mg, 0.031 mmol) were added. The reaction mixture was degassed by nitrogen sparge for 5 mm. 2M K3P04 (aq) (0.922 mL, 1.844 mmol) was quickly added and the reaction mixture heated at 100 C for 15 mm. After cooling to rt, volatiles were removed in vacuo. The cmde residue was purified with column chromatography on the Isco system (40 g, 0-100%EtOAc/Hex to afford 17C (300 mg, 0.573 mmol, 93 % yield) as a crystalline beige solid. MS ESI m/z 498.0 (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. 1190862-70-4, Ethyl 5-bromo-6-methylnicotinate, other downstream synthetic routes, hurry up and to see.
