Procedure

To a solution of 282 (100 mg, 0.244 mmol) in DCM was added triethylamine (49 mg, 0.4887 mmol). Ethane sulfonyl chloride 337 (47 mg, 0.3665 mmol) was added to the reaction and stirred it for 2 h at rt. The reaction mixture was diluted with dichloromethane and washed with water twice. The organic layer was dried over sodium sulphate and concentrated to get the crude, which was purified by flash column using 100-200 mesh silica gel. The compound was eluted at 2% methanol in chloroform as off white coloured solid 3-(3,5-difluoro-2-methoxyphenyl)-5-(1-(1-(ethylsulfonyl)piperidin-4-yl)-1H-pyrazol-4-yl)-1H-pyrrolo[2,3-b]pyridine 338. 1H NMR (400 MHz, CDCl3) δ: 9.58 (s, 1H), 8.52 (d, 1H), 8.17 (d, 1H), 7.84 (s, 1H), 7.72 (m, 2H), 7.09 (m, 1H), 6.82 (m, 1H), 4.31 (m, 1H), 3.96 (m, 2H), 3.68 (s, 3H), 3.06 (m, 2H), 3.00 (m, 3H), 2.29 (m, 2H), 2.14 (m, 2H), 1.40 (m, 5H), 1.25 (m, 5H) and MS ES+502.1.
