Procedure

6-(N-ethylmethylsulfonamido)-2-(4-fluorophenyl)-3-(methylcarbamoyl)pyrazolo[1,5-a]pyridin-5-yl trifluoromethanesulfonate (0.1 g, 0.17 mmol, 1 eq), N-(1-(pyridin-2-yl)cyclopropyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (0.0.65 g, 0.18 mmol, 1.1 eq), tetrakistriphenylphosphine palladium (0.0058 g, 0.0051 mmol, 0.03 eq) and cesium carbonate (0.165 g, 0.51 mmol, 3 eq) were dissolved in 1,4-dioxane (10 ml) and water (2 ml) and the reaction was heated at 90° C. for 14 hours. The solution was filtered through ciliate. Water was added to the filtrate which was then extracted with ethyl acetate. The organic layer was concentrated and the residue obtained purified by Preparative HPLC. Yield: 22 mg (26%) 1HNMR (400 MHz, CD3OD): δ 1.05 (t, J=8 Hz, 3H), 1.65-1.66 (m, 2H), 1.78-1.82 (m, 2H), 2.89 (s, 3H), 3.20 (s, 3H), 3.62 (br s, 2H), 7.28-7.30 (t, J=7.76 Hz, 2H), 7.57 (br s, 1H), 7.67 (t, J=7.72 Hz, 1H), 7.75 (d, J=8.20 Hz, 1H), 7.86-7.88 (m, 3H), 7.96 (s, 1H), 8.02 (d, J=2.09 Hz, 1H), 8.18 (br, 1H), 8.23 (s, 1H), 8.55 (d, J=5.32 Hz, 1H), 8.98 (s, 1H). LCMS: (ES+) m/z=627.2 (M+H); Method: Column-Ascentis Express C18 (5×2.1 mm-2.7 μm); Mphase A: 2% MeCN-98% H2O-10 mM NH4COOH; Mphase B: 98% MeCN—2% H2O-10 mM NH4COOH; Flow: 1 mL/Min; RT min: 1.768;
