Procedure

The title compound was synthesized according to the procedure described for the synthesis of 2-methylnicotinamide, starting from [1-(6-tert-butylpyridin-3-yl)ethyl]amine (intermediate 25) (93 mg, 0.52 mmol), 7-cyanobenzimidazole-1-acetic acid (100 mg, 0.5 mmol), HATU (198 mg, 0.52 mmol) and DIPEA (226 μL, 1.3 mmol). Water is added and the reaction is concentrated then purified by reverse phase chromatography. 1H NMR (400 MHz, DMSO-D6) δ ppm 1.26 (s, 9 H), 1.39 (d, J=7.03 Hz, 3 H), 4.87-4.97 (m, 1 H), 5.12-5.27 (m, 2 H), 7.32 (dd, J=8.01, 7.62 Hz, 1 H), 7.35 (d, J=8.20 Hz, 1 H), 7.66 (dd, J=8.30, 2.25 Hz, 1 H), 7.69 (dd, J=7.52, 0.88 Hz, 1 H), 7.99 (dd, J=8.20, 0.98 Hz, 1 H), 8.32 (s, 1 H), 8.45 (d, J=2.54 Hz, 1 H), 8.85 (d, J=7.42 Hz, 1 H). MS [MH+] calc. 362.1981 found 362.3.
