Procedure

The title compound was synthesized according to the procedure described for the synthesis of 2-methylnicotinamide, starting from [1-(6-tert-butyl-2-methoxypyridin-3-yl)ethyl]amine (intermediate 27) (85 mg, 0.48 mmol), 7-cyanobenzimidazole-1-acetic acid (96 mg 0.48 mmol) HATU (173 mg, 0.5 mmol) and DIPEA (209 μl, 1.20 mmol). The product was recovered by filtration following precipitation induced by the addition of water. (Yield 27 mg, 46%). 1H NMR (400 MHz, DMSO-D6) δ ppm 1.27 (s, 9 H), 1.32 (d, J=6.84 Hz, 3 H), 3.86 (s, 3 H), 5.02 (t, J=7.03 Hz, 1 H), 5.25 (d, J=4.69 Hz, 2 H), 6.91 (d, J=7.62 Hz, 1 H), 7.31-7.37 (m, 1 H), 7.62 (dd, J=7.62, 0.39 Hz, 1 H), 7.71 (dd, J=7.71, 1.07 Hz, 1 H), 8.01 (dd, J=8.20, 0.98 Hz, 1 H), 8.34 (s, 1 H), 8.78-8.83 (m, J=7.81 Hz, 1 H). MS [MH+] cal. 392.2086 found 392.3.
