Reference of 1215205-50-7, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 1215205-50-7 as follows.
Step 4: 1-[4-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-cyclopropanecarboxylic acid ethyl ester 1-(4-Bromo-phenyl)-cyclopropanecarboxylic acid ethyl ester (3 g, 13.mmol), bis(pinacolato)diboron (3.37 g, 16.1 mmol), and potassium acetate (2.8 g, 29.0 mmol) were combined in 1,4-dioxane (30 mL) under N2. The solution was purged with N2 for 10 minutes, then (1,1′-bis(diphenylphosphino)ferrocene)-dichloropalladium(II) (0.50 g, 0.65 mmol) was added and the reaction was heated to 80 C. for 2 hours. After aqueous workup, the crude material was purified by silica gel chromatography (0-30% EtOAc in hexanes) to give the title compound.
According to the analysis of related databases, 1215205-50-7, the application of this compound in the production field has become more and more popular.
