Reaction Conditions:
with caesium carbonate in dimethyl sulfoxide at 80; for 3 h;
Steps:
1.1 Step 1. Synthesis of 7-(2-methyl-4-nitrophenoxy)-[ 1, 2, 4itriazolo[f 5-aJpyridine.
The mixture of l-fluoro-2-methyl-4-nitrobenzene (96 mg, 0.617 mmol), [l,2,4]triazolo[l,5-a]pyridin-7-ol (100 mg, 0.740 mmol) aid cesium carbonate (482 mg, 1.48 mmol) in dimethyl sulfoxide (2.5 ml) was stirred at 80 °C for 3 hr. The resulting mixture was poured into ice water and the precipitate was filtered and dried using blowing nitrogen gas to give 4-([l,2,4]triazolo[l,5-a]pyridin-7-yloxy)-3-methylaniline as a brown solid (145 mg, 87 %).
