Procedure

To a solution of 324 (50 mg, 0.1182 mmol) in DCM was added triethylamine (17.9 mg, 0.1773 mmol). Methane sulfonyl chloride 342 (13.5 mg, 0.1182 mmol) was added to the reaction and stirred 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-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-5-(1-(1-(methylsulfonyl)piperidin-4-yl)-1H-pyrazol-4-yl)-1H-pyrrolo[2,3-b]pyridine 343. 1H NMR (400 MHz, DMSO) δ: 11.94 (s, 1H), 8.55 (d, 1H), 8.39 (m, 2H), 8.03 (s, 1H), 7.88 (d, 1H), 7.78 (d, 1H), 7.58 (m, 1H), 7.44 (d, 1H), 4.31 (m, 1H), 3.66 (m, 2H), 2.95 (s, 3H), 2.16 (m, 2H), 2.01 (m, 2H) and MS ES+502.1.
