실험 절차

This reaction was conducted in two separate vials. For the first reaction, a vial was charged with 1-bromo-3-chloro-N-(4-methoxybenzyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (57.11 mg, 0.109 mmol), (2-methoxy-4-(trifluoromethyl)phenyl)boronic acid (25.1 mg, 0.114 mmol), Pd(AmPhos)2Cl2 (3.85 mg, 5.44 μmol), potassium phosphate (69.3 mg, 0.326 mmol), 1,4-dioxane (408 μl), and water (136 μl). The vial was flushed with Ar (g), then sealed and heated in a microwave reactor for 15 min at 90° C. A second vial was charged with 1-bromo-3-chloro-N-(4-methoxybenzyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (422 mg, 0.804 mmol), (2-methoxy-4-(trifluoromethyl)phenyl)boronic acid (186 mg, 0.844 mmol), Pd(AmPhos)2Cl2 (28.5 mg, 0.040 mmol), potassium phosphate (512 mg, 2.412 mmol), 1,4-dioxane (3015 μl), and water (1005 μl). The vial was flushed with Ar (g), then sealed and heated in a Biotage Initiator microwave reactor for 15 min at 90° C. The reaction mixtures from each vial were combined, and the combined mixture was extracted with EtOAc (3×). The combined organic extracts were concentrated, and the residue was purified by chromatography on silica gel (40-g column, 20 to 60% EtOAc/Heptane) to give 3-chloro-1-(2-methoxy-4-(trifluoromethyl)phenyl)-N-(4-methoxybenzyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (Intermediate RRR; 500.9 mg, 0.808 mmol, 89% yield) as an off-white foam: 1H NMR (400 MHz, CHLOROFORM-d) δ ppm=8.15 (t, J=1.1 Hz, 1H), 7.77 (s, 1H), 7.68-7.65 (m, 2H), 7.50 (s, 1H), 7.44-7.38 (m, 2H), 7.30 (d, J=8.8 Hz, 2H), 7.27 (s, 1H), 7.04 (d, J=3.6 Hz, 1H), 6.73 (d, J=8.8 Hz, 2H), 5.11 (s, 2H), 3.76 (s, 3H), 3.73 (s, 3H); m/z (ESI) 620.2 (M+H)+.
