실험 절차

A mixture of 4-bromoisoquinolin-1-amine (126 mg, 0.565 mmol), bispinacol ester boronate (358 mg, 1.41 mmol), and potassium acetate (333 mg, 3.39 mmol) in 1,4-dioxane (4.6 mL) was sparged with N2 for 10 min. [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II), complex with dichloromethane (1:1) (23.1 mg, 0.0282 mmol) was added. The mixture was sealed under N2 and heated at 80° C. for 20 h, diluted with DCM, the contents were filtered, washed with DCM, and concentrated. The crude product was mixed with 2-(4-((2-chloro-4-morpholinothieno[3,2-d]pyrimidin-6-yl)methyl)piperazin-1-yl)-2-methylpropanamide (124 mg, 0.282 mmol), a 1 M solution of sodium carbonate (0.85 mL) and 1,4-dioxane (3.4 mL, 44 mmol). The mixture was sparged with N2 for 10 min. Palladium acetate (6.342 mg, 0.02825 mmol) and a 1.0 M solution of tri-tert-butylphosphine in toluene (0.0565 mL) were added. The mixture was sealed under N2 and heated at 85° C. for 6 h, diluted with DCM, the contents were filtered, and concentrated. The residue was purified with flash chromatography. The fractions containing the desired product were collected, concentrated, and purified with reverse-phase HPLC to give 108 (25 mg, 16%). LCMS: M+H+=467. 1H NMR (400 MHz, CDCl3) δ 8.91 (d, J=8.6, 1H), 8.67 (s, 1H), 7.85 (d, J=8.3, 1H), 7.71-7.64 (m, 1H), 7.53 (t, J=7.3, 1H), 7.34 (s, 1H), 7.10 (s, 1H), 5.29 (s, 2H), 5.20 (s, 1H), 4.10-3.99 (m, 4H), 3.87 (dd, J=9.1, 4.6, 6H), 2.61 (s, 8H), 1.24 (s, 6H)
