Reaction Steps

To a solution of N-(2-chloroethyl)-2-nitrobenzamide (3.63 g) in acetonitrile (100 ml) was slowly added 40% potassium fluoride on alumina (10 g). This slurry was stirred at ambient temperature for 24 hours. The potassium fluoride on alumina was filtered through a bed of celite, washed with ethyl acetate. The solvent was evaporated to give 2-(2,5-oxazolinyl)nitrobenzene (3.0 g).
