Procedure

The title compound was synthesized according to the procedure described for the synthesis of 2-methylnicotinamide, starting from [1-(6-tert-butyl-4-methylpyridin-3-yl)ethyl]amine (intermediate 28) (52 mg, 0.27 mmol), 7-cyanobenzimidazole-1-acetic acid (54.4 mg, 0.27 mmol), HATU (108 mg, 0.28 mmol) and DIPEA (117 μL, 2.5 mmol). Water is added and the reaction is concentrated then purified by reverse phase chromatography. (Yield 31.3 mg, 31%). 1H NMR (400 MHz, DMSO-D6) δ ppm 1.27 (s, 9 H), 1.42 (d, J=7.03 Hz, 3 H), 2.29 (s, 3 H), 5.03-5.12 (m, 1 H), 5.13-5.27 (m, 2 H), 7.17 (s, 1 H), 7.34 (dd, J=8.11, 7.71 Hz, 1 H), 7.71 (dd, J=7.62, 0.78 Hz, 1 H), 8.01 (dd, J=8.01, 0.98 Hz, 1 H), 8.34 (s, 1 H), 8.47 (s, 1 H), 8.88 (d, J=7.81 Hz, 1 H). MS [MH+] calc. 376.2137 found 376.3.
