Reaction Steps

Cyclopropanecarboxylic acid (5-bromo-[1,2,4]triazolo[1,5-a]pyridin-2-yl)-amide (0.05 g, 0.178 mmol), 1-propyl-1H-pyrazole-4-boronic acid, pinacol ester (0.054 g, 0.231 mmol) and dimethylacetamide (1 mL) were added to a microwave tube containing a stirrer bar, potassium phosphate solution (0.5M in water, 0.7 mL, 0.356 mmol) and tetrakis(triphenylphosphine)palladium (0.02 g, 0.018 mmol). The reaction was heated to 150° C. for 10 min under microwave heating. The crude was purified straight away by preparatory chromatography after filtration. LCMS method: 2, RT: 3.75 min; MI: 311 [M+1]; NMR 1H (DMSO): 0.80-0.88 (m, 7H), 1.78-1.90 (m, 2H), 2.05 (brs, 1H), 4.16 (t, 2H), 7.52 (dd, 1H), 7.55 (d, 1H), 7.66 (t, 1H), 8.51 (s, 1H), 8.86 (s, 1H), 11.11 (brs, 1H).
