Procedure

To a solution of 3-(1-methyl-1H-indazol-5-yl)pyridin-2(1H)-one (13.0 mg, 0.055 mmol), (S)-methyl 2-(2-bromo-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyacetate (22 mg, 0.046 mmol), trans-N1,N2-dimethylcyclohexane-1,2-diamine (9 μL, 0.055 mmol) and potassium carbonate (13 mg, 0.091 mmol) in DMF (0.5 mL) was added copper(I) iodide (5.0 mg, 0.026 mmol). The mixture was degassed with N2 for 5 minutes and then heated at 110° C. for 3 h. The mixture was then diluted with EtOAc, extracted with H2O, brine, dried over Na2SO4, filtered and concentrated and purified by flash column chromatography (silica gel, 0 to 100% ethyl acetate/hexanes) to give the product. LCMS-ESI+ (m/z): [M+H]+ calcd for C34H32ClN4O4S: 627.18; Found: 627.2.
