Procedure

The title compound was synthesized in two steps. The first as described for Intermediate example I-97, starting from 5-(methoxycarbonyl)pyridine-2-carboxylic acid and 4,4,4-trifluorobutan-1-amine, and the second as described for Intermediate example I-98 at 55° C., starting from the product received in the first step which was first purified by column chromatography using a gradient of ethyl acetate in heptane. Total yield (two steps) 34%; 1H NMR (400 MHz, DMSO-d6) δ ppm 9.16 (t, 1 H), 9.09 (dd, 1 H), 8.44 (dd, 1 H), 8.14 (dd, 1 H), 3.38 (q, 2 H), 2.20-2.36 (m, 2 H), 1.71-1.81 (m, 2 H); MS (ESI) m/z 277[M+H+], m/z 275[M−H+];
