Procedure

Synthesized according to general procedure 17, method C using THF as solvent. To a solution of 4-(piperidin-4-yl)-N-(thiazol-2-yl)benzenesulfonamide (0.35 g, 1.08 mmol) and 2-(5-chloro-1H-pyrrolo[2,3-b]pyridin-1-yl)acetic acid (0.25 g, 1.19 mmol) in THF (6 mL) was added HATU (0.533 g, 1.40 mmol) followed by the addition of DIEA (0.279 g, 2.16 mmol) at 0° C. under inert atmosphere. The reaction was quenched with water after 15 minutes, the layers were separated and the aqueous layer was extracted with DCM. The combined organic layers were dried over Na2SO4, filtered and concentrated. Purification via silica gel chromatography using 0-3% methanol in DCM gave 4-(1-(2-(5-chloro-1H-pyrrolo[2,3-b]pyridin-1-yl)acetyl)piperidin-4-yl)-N-(thiazol-2-yl)benzenesulfonamide (0.26 g, 46% yield). 1H NMR (400 MHz, DMSO-d6) δ 12.71 (s, 1H), 8.22 (d, J=2.3 Hz, 1H), 8.10 (d, J=2.3 Hz, 1H), 7.75 (d, J=8.4 Hz, 2H), 7.57 (d, J=3.5 Hz, 1H), 7.44 (d, J=8.4 Hz, 2H), 7.26 (d, J=4.6 Hz, 1H), 6.83 (d, J=4.6 Hz, 1H), 6.49 (d, J=3.5 Hz, 1H), 5.25 (d, J=2.6 Hz, 2H), 4.44 (d, J=12.9 Hz, 1H), 4.16 (d, J=12.8 Hz, 1H), 3.24 (t, J=11.7 Hz, 1H), 2.95-2.88 (m, 1H), 2.70 (t, J=11.7 Hz, 1H), 1.91-1.66 (m, 3H), 1.55-1.45 (m, 1H). LC/MS (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)), m/z: M+1 obs=516.5; tR=1.57 min.
