Cesium carbonate → 2-(3-Azido-1-trifluoromethylpropoxy)-6-trifluoromethylnicotinonitrile

Participants

Reaction Steps

A mixture of 2-chloro-6-(trifluoromethyl)nicotinonitrile (0.675 g, 3.27 mmol) and 4-azido-1,1,1-trifluoro-2-butanol (0.552 g, 3.26 mmol) in DMF (8.5 mL) was treated with caesium carbonate (2.18 g, 6.69 mmol) at ambient temperature. After 20 h, the mixture was diluted with water and extracted with diethyl ether. The combined organic extracts were washed (water, brine), dried, and-evaporated to give the product as a brown oil (1.01 g, 90%).
