To a vial containing mixtures of compound 1I and 1J (100 mg, 0.4 mmol) obtained from previous step in dioxane (1 mL) were added CuI (15.6 mg, 0.08 mmol), K3PO4 (174 mg, 0.82 mmol), 1,2-cyclohexyldiamine (4.7 mg, 0.08 mmol) and compound 1E (136 mg, 0.49 mmol). The vial was sealed, and heated at 110° C. for 14 hr, cooled to RT. The solid was filtered off, and filtrate was concentrated. Purification by silica gel chromatography (5% to 100% EtOAc in hexanes, then 10% methanol in EtOAc) provide the mixtures of title compounds 1K and 1L (total 98 mg) as a yellow oil. MS (ES) m/z 395 [M+H]+.
