To 1-3.2 (32.0 g, 142 mmol) in anhydrous dioxane (400 mL) is added R8 (S4.4 g, 241 mmol) andpotassium acetate ( 41.6 g, 424 mmol). The mixture is purged with Argon, [1 , 1’Bis(diphenylphosphino)ferrocene]dichloropalladium(IJ) as a complex with dichloromethane ( 11 .2g, 14 mmol) is added and the mixture is heated to 90 C for 2 h. The reaction mixture is diluted with ethyl acetate and water, the organic layer is washed with water, dried over MgS04 and concentrated. The residue is purified via flash chromatography (cyclohexane I EA = 70:30). Yield72%, m/z 274 [M+H]+, 11 0.67 min, LC-MS Method Y011_S01.
The synthetic route of 897957-06-1 has been constantly updated, and we look forward to future research findings.
