実験手順

To a solution of (S)-2-(2-bromo-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyethyl pivalate (51 mg, 0.095 mmol) and 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazolo[3,4-b]pyridine (28 mg, 0.123 mmol) in degassed 1,4-dioxane (250 μL) and water (25 μL) was added aqueous K2CO3 (95 μL of a 2.0 M solution) and tetrakis(triphenylphosphine)palladium(0) (6 mg, 0.005 mmol). The reaction mixture was heated at 100° C. for 6 h, cooled and partitioned between ethyl acetate and brine. The organic layer was separated, dried over Na2SO4 and concentrated. The crude material was used without any further purification. LCMS-ESI+: calc'd for C31H34ClN4O3S: 577.2 (M+H+); Found: 577.3 (M+H+).
