Procedure

2-(4-fluorophenyl)-N-methyl-5-(3-(1-phenylcyclobutylcarbamoyl)phenyl)pyrazolo[1,5-a]pyridine-3-carboxamide was prepared from 3-(2-(4-fluorophenyl)-3-(methylcarbamoyl)pyrazolo[1,5-a]pyridin-5-yl)benzoic acid (0.070 g, 0.14 mmol) and 1-phenylcyclobutanamine hydrochloride (0.040 g, 0.20 mmol). 1H NMR (500 MHz, DMSO-D6) δ ppm 9.21 (s, 1H), 8.90 (d, J=7.02 Hz, 1H), 8.30 (s, 1H), 8.09 (s, 1H), 7.96-8.03 (m, 2H), 7.88-7.96 (m, 3H), 7.63 (t, J=7.63 Hz, 1H), 7.53 (d, J=7.63 Hz, 2H), 7.48 (dd, J=7.32, 1.83 Hz, 1H), 7.30-7.37 (m, 4H), 7.21 (t, J=7.32 Hz, 1H), 2.82 (d, J=4.58 Hz, 3H), 2.63-2.71 (m, 2H), 2.58 (ddd, J=12.13, 8.62, 6.10 Hz, 2H), 2.03-2.11 (m, 1H), 1.84-1.93 (m, 1H). LCMS: retention time: 3.225 min. LC data was recorded on a Shimadzu LC-10AS liquid chromatograph equipped with a Phenomenex-Luna, 10u, C18, 4.6×30 mm column using a SPD-10AV UV-Vis detector at a detector wave length of 220 nM. The elution conditions employed a flow rate of 4 mL/min, a gradient of 100% solvent A/0% solvent B to 0% solvent A/100% solvent B, a gradient time of 3 min, a hold time of 1 min, and an analysis time of 4 min where solvent A was 10% CH3OH/90% H2O/10 mM TFA and solvent B was 10% H2O/90% CH3OH/10 mM TFA. MS data was determined using a Micromass Platform for LC in electrospray mode. m/z 519 (MH+).
