Procedure

Crude (3-(3-(2-fluorophenyl)-1-tosyl-1H-pyrrolo[2,3-b]pyridin-5-yl)phenyl)(morpholino)methanone from last step was dissoled in methanol (1 mL) and potassium hydroxide (50% w/v, 0.038 mL, 0.136 mmol) was added to the solution. The resulting mixture was stirred at room temperature for 30 minutes before being diluted with water and extracted with ethyl acetate. The organic layers were combined, dried over sodium sulfate, filtered and concentrated to dryness. The crude product was then dissolved in DMSO and purified by mass triggered reverse phase HPLC to afford pure (3-(3-(2-fluorophenyl)-1H-pyrrolo[2,3-b]pyridin-5-yl)phenyl)(morpholino)methanone (5.6 mg, 21% yield from (3-(3-iodo-1-tosyl-1H-pyrrolo[2,3-b]pyridin-5-yl)phenyl)(morpholino)methanone) as light brown syrup. 1H NMR (500 MHz, DMSO-d6) δ 3.60 (m, br, 8H), 7.33 (m, 3H), 7.39 (m, 1H), 7.55 (t, J=7.5 Hz, 1H), 7.74 (m, 1H), 7.84 (m, 3H), 8.28 (m, 1H), 8.61 (d, J=2.5 Hz, 1H), 12.17 (s, 1H). MS: m/z 402.1 (M+H+).
