実験手順

To a degassed suspension of 2-(4-((2-chloro-4-morpholinothieno[3,2-d]pyrimidin-6-yl)methyl)piperazin-1-yl)-2-methylpropanamide (90.0 mg 0.205 mmol), 4,4,5,5-tetramethyl-2-(2-methylbenzofuran-3-yl)-1,3,2-dioxaborolane (120 mg, 0.46 mmol) in acetonitrile (2 mL) was added 2 M aqueous solution of sodium carbonate (0.20 mL) and 1M aqueous solution of potassium acetate (0.2 mL). The mixture was then heated in a microwave at 140° C. for 30 minutes. The reaction mixture was diluted with water and EtOAc. The aqueous layer was extracted with EtOAc. The combined extracts were washed with brine, dried over Na2SO4, filtered and concentrated. The crude product was purified by RP-HPLC to give 140 (33.6 mg, 30.6%). LCMS: M+H+=535.2. 1H-NMR (400 MHz, DMSO-d6): δ 8.45 (m, 1H), 7.55 (m, 1H), 7.42 (s, 1H), 7.31 (m, 2H), 7.05 (s, 1H), 6.93 (s, 1H), 3.95 (m, 4H), 3.86 (s, 2H), 3.83 (m, 4H), 2.84 (s, 3H), 2.42-2.63 (m, 8H), 1.08 (s, 6H)
