In a sealable tube, to 5-bromo-1-[(2,5-difluorophenyl)acetyl]-2,3-dihydro-1H-indole (0.700 g, 1.988 mmol), bispinacolatodiboron (0.606 g, 2.385 mmol) and potassium acetate (0.585 g, 5.96 mmol) was added 1,4-Dioxane (15 mL) and the mixture was degassed with N2 for 10 minutes. PdCl2(dppf)-CH2Cl2Adduct (0.081 g, 0.99 mmol) was added and the reaction mixture was sealed and stirred for 48 hours at 100° C. The mixture was cooled to room temperature and treated with 5 mL of water, 3-bromothieno[3,2-c]pyridin-4-amine (0.501 g, 2.186 mmol) and sodium bicarbonate (167 mg, 1.988 mmol). The mixture was degassed with N2 for 10 minutes. PdCl2(dppf)-CH2Cl2 adduct (0.085 g, 0.104 mmol) was added and the reaction mixture was stirred overnight at 100° C. The mixture was poured onto water and ethyl acetate, then filtered. The filtrate was poured into a separatory funnel. The organic layer was separated and the aqueous layer was further extracted with ethyl acetate. The combined organic layers were washed with brine, dried (MgSO4), filtered and concentrated. Purified by Analogix silica gel cartridge 25/40, eluting with a gradient of 0-100% EtOAc/hexane. The compound came out at 100% EtOAc in 10 minutes. The pure fractions with the compound were combined. The solvents were evaporated and dried to give an off-white solid (526 mg) of the title compound 3-{1-[(2,5-difluorophenyl)acetyl]-2,3-dihydro-1H-indol-5-yl}thieno[3,2-c]pyridin-4-amine.
