Procedure
(racemic)-5-Bromo-3-[trans-2-(1-methylethyl)-1,1-dioxidotetrahydro-2H-thiopyran-4-yl]-1H-indole-7-carboxamide (60 mg, 0.145 mmol) was placed in a microwave vial and dissolved with 1,4-Dioxane (2 mL) and Water (1 mL). 2-Furanylboronic acid (33 mg, 0.29 mmol) and K2CO3 (60 mg, 0.44 mmol) were added. Argon was bubbled into the mixture for 10 mins, stirring. PdCl2(dppf) (5.60 mg, 0.012 mmol) was added, and argon was bubbled another 10 mins. The vial was sealed and put under microwave 5 mins at 100° C. with high absorption parameter. The crude was run through a thiol-SPE cartridge eluting with 2 mL of methanol and the eluted solvents are evaporated. The brown oil was dissolved in 2-3 mL of DMSO, and on a Gilson HPLC. The desired fractions were concentrated, giving 32 mg of the title compound.
