A pressure tube was charged with benzyl {7-bromo-2-[({4-[(3R,4S,5S)-3-[(tert-butoxycarbonyl)amino]-5-methyl-4-(1H-1,2,3-triazol-1-yl)piperidin-1-yl]pyridin-3-yl}amino)carbonyl]quinolin-3-yl}carbamate (15 mg, 0.020 mmol), K3PO4 (8.4 mg, 0.04 mmol), 1,4-dioxane (0.3 mL), water (0.04 mL) and 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3,6-dihydro-2H-pyran (6.3 mg, 0.03 mmol). The reaction mixture was purged with nitrogen for 10 min., then dicyclohexyl(2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine-(2′-aminobiphenyl-2-yl)(chloro)palladium (1:1) (1.6 mg, 0.002 mmol) was added. The pressure tube was sealed and the reaction mixture was heated at 90° C. for 30 min then allowed to cool. The mixture was then filtered and purified by preparative LCMS (pH=10 method; XBridge™ preparative C18 5 μm OBD™ column, 30×10 mm, 60 mL/min., eluting with a gradient of MeCN and water with 0.1% NH4OH) to give the sub-title compound as a light yellow powder (4 mg, 27%). LCMS calc. for C41H46N9O6 (M+H)+: m/z=760.4. Found: 760.5.
