Reaction Steps
A mixture of 1,3,5-trifluoro-2-nitrobenzene (2.2 mL, 18.6 mmol), 2-bromo-4-methylimidazole (3 g, 18.6 mmol) and K2CO3 (5.66 g, 41 mmol) in 80 mL DMF was stirred at room temperature overnight. The mixture was diluted with ethyl acetate and washed with water. Standard work up procedure followed by column purification using 10% ethyl acetate in dichloromethane as eluent provided 3.18 g (54% yield) of the product as a yellow powder. EIMS 317.9 [M+H]+.
