Methanol (1 mL) was added to erode (3-(3-(2,6-dimethoxyphenyl)-1-tosyl-1H-pyrrolo[2,3-b]pyridin-5-yl)phenyl)(morpholino)methanone from step 1 and potassium hydroxide (50% w/v, 0.038 mL, 0.34 mmol) was added to the resulting solution. The mixture was stirred for 30 minutes at room temperature before being diluted with water and extracted with ethyl, acetate. The organic layers were combined, dried over sodium sulfate, filtered and concentrated to dryness. Silica gel chromatography afforded (3-(3-(2,6-dimethoxyphenyl)-1H-pyrrolo[2,3-b]pyridin-5-yl)phenyl)(morpholino)methanone (7) (31% yield from (3-(3-iodo-1-tosyl-1H-pyrrolo[2,3-b]pyridin-5-yl)phenyl)(morpholino)methanone) as light yellow solids. 1H NMR (500 MHz, CD2OD) δ 3.65 (m, br, 8H), 3.75 (s, 6H), 6.77 (d, J=8.5 Hz, 2H), 7.31 (t, J=8.5 Hz, 1H), 7.39 (m, 1H), 7.46 (s, 1H), 7.55 (t, J=7.5 Hz, 1H), 7.67 (m, 1H), 7.74 (m, 1H), 7.91 (d, J=2.0 Hz, 1H), 8.45 (d, J=2.0 Hz, 1H). MS; m/z 444.1 (M+H+).
