実験手順

To 5-bromo-3-(1,1-dioxidotetrahydro-2H-thiopyran-4-yl)-1H-indole-7-carboxamide (400 mg, 1.08 mmol) in dioxane and water (4 mL/1 mL) was added 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-thiophenecarbaldehyde (462 mg, 1.94 mmol), Pd(PPh3)4 (100 mg) and K2CO3 (447 mg, 3.24 mmol). The reaction mixture was heated at 150° C. for 20 minutes by microwave irradiation. The organic phase was concentrated and redissolved in DMSO (10 mL). The resulting solution was split to eight. NaBH3CN (30 mg), ZnCl2 (30 mg) and -[(1,1-dimethylethyl)oxy]ethyl}methylamine (50 mg) were added. The mixture was heated at 100° C. for 30 minutes which was then filtered and purified by HPLC with TFA to afford the title compound (15 mg).
