Reaction Steps

To 5-bromo-3-(1,1-dioxidotetrahydro-2H-thiopyran-4-yl)-1H-indole-7-carboxamide (80 mg, 0.216 mmol) in dioxane and water (4 mL/1 mL) was added (3-formylphenyl)boronic acid (45 mg), Pd(PPh3)4 (25 mg) and K2CO3 (104 mg). The reaction mixture was redissolved in DMSO (2 mL). To the resultant mixture zinc chloride (30 mg), NaCNBH3 (30 mg) and (2s)-3-methyl-2-butanamine (50 mg) were added. The mixture was heated to 100° C. for 30 minutes by microwave irradiation and purified by HPLC with TFA to afford the title compound (16 mg).
