A mixture of 5-bromothieno[2,3-d]pyrimidin-4-amine (90 mg, 0.391 mmol) and 1-[(3-methylphenyl)acetyl]-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3-dihydro-1H-indole (148 mg, 0.391 mmol) in 1,4-Dioxane (6 mL) and sat. aq. NaHCO3 (2 mL) was degassed with N2 for 10 minutes. PdCl2(dppf)-CH2Cl2 adduct (15.97 mg, 0.020 mmol) was added, and the reaction mixture was stirred overnight at 100° C. in a sealed vessel. The reaction was cooled down to room temperature and poured onto water. The aqueous mixture was filtered, and the solid in the filter was purified via flash chromatography on SiO2 (gradient: 100% Hexanes to 100% EtOAc) to afford the desired product (119 mg) as a white solid. LC-MS (ES) m/z=401.3 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ 2.31 (s, 3H), 3.22 (t, J=8.46 Hz, 2H), 3.84 (s, 2H), 4.23 (t, J=8.46 Hz, 2H), 7.04-7.16 (m, 3H), 7.20-7.29 (m, 2H), 7.34 (s, 1H), 7.42 (s, 1H), 8.17 (d, J=8.34 Hz, 1H), 8.34 (s, 1H).
