Yield:1158227-59-8 71%
Reaction Conditions:
with palladium bis[bis(diphenylphosphino)ferrocene] dichloride;potassium acetate in 1,4-dioxane at 95; for 24 h;
Steps:
1.5 Synthesis of intermediate 1-2
Intermediate 1-1 (3.1 g, 0.008 mol) in bis (pinacolato) dibron (2.5 g, 0.010 mol) PdCl2(dppf) (0.3 g, 0.0004 mol), potassium-acetate (2.2 g, 0.016 mol) in 1,4-dioxane 80 mL was reacted with stirring for 24 hours at 95 ° C. After the reactioncooled to H20: After layer separation the MC column purification (n-Hexane: MC) tothe intermediate 1-2 was obtained 2.4 g (yield 71%).
