Versuchsvorschrift
Following General Procedure B, 9-bromo-8-methoxythieno[2,3-c]quinolin-4(5H)-one (500 mg, 1.5 mmol) was reacted with N-(2-hydroxyethyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzenesulfonamide (450 mg, 1.5 mmol) to afford the desired product (130 mg, 20%) as an off-white solid: 1H NMR (300 MHz, DMSO-d6) δ 11.93 (s, 1H), 7.94 (d, J=8.4 Hz, 2H), 7.78-7.74 (m, 2H), 7.58-7.42 (m, 4H), 5.74 (d, J=5.4 Hz, 1H), 4.78 (t, J=5.6 Hz, 1H), 3.71 (s, 3H), 3.45 (q, J=6.1 Hz, 2H), 2.93 (q, J=6.2 Hz, 2H).
