実験手順

To a solution of (S)-ethyl 2-tert-butoxy-2-(7-(4-chlorophenyl)-2-(2-chloropyridin-4-yl)-5-methylbenzo[d]thiazol-6-yl)acetate (32.0 mg, 0.061 mmol) and 7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2H-pyrido[3,2-b][1,4]oxazin-3(4H)-one (20.0 mg, 0.073 mmol) in dioxane (0.5 mL) was added Pd(PPh3)4 (3.5 mg, 0.003 mmol) and 2N K2CO3 (127 μL, 0.255 mmol). The reaction was degassed for 5 minutes with N2 and then heated at 100° C. for 10 h. After cooling, the reaction mixture was 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 desired product. LCMS-ESI+ (m/z): [M+H]+ calcd for C34H32ClN4O5S: 643.2; found: 643.3.
