Reaction Steps

Using similar reaction conditions as described in step-iii of example-1, N-(5-(3-(1-(4-fluorophenethyl)-1H-pyrazol-4-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridin-5-yl)-2-methoxyphenyl) methanesulfonamide (25 mg, 0.0379 mmol) was hydrolyzed by lithium hydroxide (15 mg, 0.379 mmol) in THF/methanol/water (2/2/1 ml) to yield 8 mg (40.0% yield) of the titled compound. 1H NMR (DMSO-d6, 300 MHz): δ 11.7 (s, 1H), 9.034-9.035 (d, 1H), 8.43-8.42 (d, 1H), 8.20 (s, 1H), 8.14 (s, 1H), 7.87 (s, 1H), 7.69-7.68 (d, 2H), 7.58-7.56 (m, 2H), 7.26-7.18 (m, 3H), 7.11-7.05 (m, 2H), 4.39-4.35 (t, 2H), 3.89 (s, 3H), 3.18-3.13 (t, 2H), 3.00 (s, 3H). MS: m/z=506.5 (M+1), HPLC: 96.65% in method B.
