Procedure

A solution of 1-(pyridin-2-yl)-4,5,6,7-tetrahydro-1H-imidazo[4,5-c]pyridine (0.050 g, 0.25 mmol), 2-chloro-3-trifluoromethyl benzoic acid (0.056 g, 0.25 mmol), HATU (0.10 g, 0.26 mmol, and DIPEA (0.09 mL, 0.50 mmol) in DMF (2 mL) was stirred for 30 min. The reaction was diluted with EtOAc (15 mL) and washed with H2O (3×10 mL). The organic layers were combined, dried (Na2SO4), and concentrated. Chromatography of the resulting residue (SiO2; MeOH(NH3):DCM) gave the title compound (22 mg, 22%). 1H NMR (400 MHz, CDCl3) δ 8.52 (dd, J=4.9, 1.8 Hz, 1H), 8.02 (d, J=18.1 Hz, 1H), 7.92-7.71 (m, 2H), 7.58-7.40 (m, 2H), 7.37-7.28 (m, 2H), 5.12-4.78 (m, 1H), 4.51-4.19 (m, 2H), 3.97 (ddd, J=13.4, 12.7, 9.9 Hz, 1H), 3.61-3.45 (m, 1H), 3.27-2.82 (m, 2H). MS (ESI): mass calculated for C19H14ClF3N4O, 406.1. m/z found 407.1 [M+H]+.
