Versuchsvorschrift

To a 48 mL pressure bottle containing Intermediate 75A (558.6 mg, 1.46 mmol) was added 4,4,4′,4′,5,5,5′,5′-octamethyl-2,2′-bi(1,3,2-dioxaborolane) (569.2 mg, 2.24 mmol), potassium acetate (584.3 mg, 5.95 mmol), and anhydrous DMSO (11 mL). The reaction mixture was flushed with argon and treated with PdCl2(dppf).CH2Cl2 (59.1 mg, 0.081 mmol). The reaction mixture was heated to 85° C. for 1 h and then at 105° C. for 1.5 h to give conversion to the desired product. LC/MS (Condition B): ret. T=4.29 min, (M+H)+ 291.99, 292.99.
