Reaction Steps

Compound 2-(5-fluoropyridin-3-yl)-6-methoxy-4H-thieno[3,2-b]indole (W309) was synthesized using the same procedure for the preparation of W270 from 1-bromo-4-methoxy-2-nitrobenzene (104 mg, 0.45 mmol), 2,5-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)thiophene (168 mg, 0.5 mmol), and 3-bromo-5-fluoropyridine (105 mg, 0.6 mmol), as a yellow solid (10 mg, total yield 6.7%). 1H NMR (400 MHz, acetone-d6) δ 10.36 (brs, 1 H), 8.76 (s, 1 H), 8.33 (s, 1 H), 7.83 (m, 2 H), 7.77 (m, 1 H), 7.62-7.60 (m, 1 H), 7.02 (s, 1 H), 6.80 (d, J=8.8 Hz, 1 H), 3.86 (s, 3 H); MS (ESI) m/z 299 (M+H+).
