Procedure

To a solution of 282 (50 mg, 0.122 mmol) in acetone was added potassium carbonate (25 mg, 0.244 mmol) and 2-bromo ethanol (18.3 mg, 0.146 mmol) and stirred for 12 h at 60° C. The reaction was filtered through celite bed and washed with ethyl acetate. The organic layer was concentrated to get the crude, which was purified by neutral alumina and the compound was eluted at 2% methanol in chloroform as half white coloured solid 2-(4-(4-(3-(3,5-difluoro-2-methoxyphenyl)-1H-pyrrolo[2,3-b]pyridin-5-yl)-1H-pyrazol-1-yl)piperidin-1-yl)ethanol 347. 1HNMR (400 MHz, DMSO) δ: 12.04 (s, 1H), 8.54 (d, 1H), 8.31 (s, 1H), 8.18 (d, 1H), 7.93 (s, 1H), 7.81 (d, 1H), 7.22 (m, 2H), 4.39 (m, 1H), 4.10 (m, 1H), 4.00 (m, 1H), 3.60 (s, 3H), 3.50 (m, 2H), 2.96 (d, 2H), 2.42 (m, 2H), 2.13 (m, 2H), 1.99 (m, 3H), 1.16 (t, 1H) and MS ES+454.0.
