HCID 67481381N-[2-(2-Amino-[1,2,4]triazolo[1,5-a]pyridin-8-yl)-phenyl]-N-methyl-methanesulfonamide

Procedure

N-[2-(2-Amino-[1,2,4]triazolo[1,5-a]pyridin-8-yl)-phenyl]-N-methyl-methanesulfonamide was prepared from 8-bromo-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine (625.0 mg, 2.934 mmol) and N-methyl-N-[2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-phenyl]-methanesulfonamide (1000.0 mg, 3.2133 mmol) in a manner analogous to Example 2c. Product was isolated as white solid (0.479 g, 51%). 1H NMR (400 MHz, (D3C)2SO, δ, ppm): 8.52 (d, J=6.5 Hz, 1H), 7.62 (d, J=7.4 Hz, 1H), 7.55-7.42 (m, 3H), 7.35 (d, J=7.2 Hz, 1H), 6.94 (t, J=7.1 Hz, 1H), 5.94 (s, 2H), 3.10 (s, 3H), 2.85 (s, 3H). MP=209-211° C. MS=318 (MH)+.
