Related Products of 865664-04-6, Adding some certain compound to certain chemical reactions, such as: 865664-04-6, name is 2-Chloro-3-cyclopropylpyridine,molecular formula is C8H8ClN, 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 865664-04-6.

Palladium(ll) acetate (61 mg, 0.27 mmol) and di-fert-butyl[3,4,5,6-tetramethyl-2′,4′,6′-tri(propan-2-yl)biphenyl-2-yl]phosphane (130 mg, 0.27 mmol) were added to a mixture of C6 (615 mg, 4.00 mmol), C5 (1 .0 g, 2.6 mmol) and cesium carbonate (2.6 g, 8.0 mmol) in 1,4-dioxane (25 mL). The reaction mixture was stirred at 120 C under microwave irradiation for 5 hours, then diluted with ethyl acetate (50 mL) and filtered. After removal of solvents in vacuo, the residue was purified via silica gel chromatography (Gradient: 0% to 25% ethyl acetate in petroleum ether) to provide the product as a yellow gum. Yield: 900 mg, 1 .8 mmol, 69%.
