Reaction Steps

Using similar reaction conditions as described in step-iii of example-1, N-(4-(3-(1-(3,5-difluorobenzyl)-1H-pyrazol-4-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridin-5-yl)-2-methoxyphenyl)methane sulfonamide (95 mg, 0.14 mmol) was hydrolyzed by lithium hydroxide (18 mg, 0.42 mmol) in THF/methanol/water (2/2/1 ml) to yield 38 mg (52.1% yield) of the titled compound after purification by preparative TLC (Silicagel-1000 micron) using 5% methanol in chloroform as eluent. 1H NMR (DMSO-d6, 300 MHz): δ 11.8 (s, 1H), 8.95 (s, 1H), 8.559-8.552 (d, 1H), 8.42 (s, 1H), 8.367-8.361 (d, 1H), 7.99 (s, 1H), 7.77-7.76 (d, 1H), 7.38 (s, 1H), 7.35-7.32 (m, 2H), 7.20-7.10 (m, 1H), 6.97-6.95 (d, 2H), 5.39 (s, 2H), 3.94 (s, 3H), 2.96 (s, 3H). MS: m/z=510.1 (M+1), HPLC: 87.42% in method B.
