To a warm (70° C.), stirred, solution of (3,5-Dimethyl-pyridin-2-ylmethyl)-isoquinolin-1-ylmethyl-piperidin-4-yl-amine (0.101 g, 0.28 mmol) and DIPEA (0.29 mL, 1.67 mmol) in DMF (3 mL) was added freshly prepared imidazole-1-carboxylic acid (1H-imidazol-2-yl)-amide (2 equivs). After 1 hour, the mixture was cooled to room temperature, diluted with brine (5 mL) and extracted with CH2Cl2 (4×10 mL). The combined organic extracts were washed with water (5×10 mL), dried (Na2SO4) and concentrated. Purification of the crude material by column chromatography on silica gel (20:1:1 CH2Cl2-MeOH—NH4OH) provided 102 mg (75%) of COMPOUND 274 as a white solid. 1H NMR (CDCl3) δ 1.60-1.79 (m, 2H), 1.96-2.03 (m, 5H), 2.27 (s, 3H), 2.66-2.75 (m, 3H), 3.85 (s, 2H), 4.26-4.30 (m, 4H), 6.69 (s, 2H), 7.22-7.26 (m, 2H), 7.32-7.37 (m, 1H), 7.53-7.62 (m, 2H), 7.75 (d, 1H, J=8.1 Hz), 7.87 (d, 1H, J=8.7 Hz), 8.18 (s, 1H), 8.40 (d, 1H, J=6.0 Hz); 13C NMR (CDCl3) δ 18.32, 18.49, 27.57, 44.75, 54.92, 55.42, 58.07, 120.85, 126.62, 126.77, 127.23, 128.09, 130.13, 132.31, 133.26, 136.67, 139.17, 141.76, 145.51, 146.85, 154.35, 155.80, 159.42; ES-MS m/z 470 (M+H).
