Using the same protocol used to prepare compound I-A-492, 3-(1-(2,3-difluorophenyl)-1H-tetrazol-5-yl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-amine and tert-butyl 4-(5-bromothiazol-2-yl)piperidine-1-carboxylate were reacted together in a PdCl2(dppf)-2-mediated coupling to produce 3-(1-(2,3-difluorophenyl)-1H-tetrazol-5-yl)-5-(2-(piperidin-4-yl)thiazol-5-yl)pyridin-2-amine; 1H NMR (DMSO-d6): 8.46 (d, J=2.3 Hz, 1H), 7.90-7.48 (m, 5H), 3.40-3.22 (m, 3H), 3.11-2.92 (m, 2H), 2.22-2.10 (m, 2H), 1.99-1.83 (m, 2H); ES-MS: m/e=441.1 (M+H).
