Procedure
To a mixture of (3-chloro-5-trifluoromethyl-2-pyridyl)methylamine (1 mmol) in tetrahydrofuran (5 ml) was added triethylamine (1 mmol) at room temperature and the mixture was stirred at room temperature for 1.5 hour. The mixture was added to a solution of 2-furoyl chloride (1 mmol) in tetrahydrofuran (5 ml) at room temperature and left to stir at room temperature overnight. The mixture was evaporated to dryness and the residue washed with water. The solid was filtered, washed with diethyl ether/light petroleum (b.p. 60-80° C.) and dried to give the title product, 1H N.M.R. (CDCl3) δ (ppm) 4.9 (2H, d), 6.55 (1H, m), 7.2 (1H, m), 7.5 (1H, s), 7.8 (1H, br.s), 8.0 (1H, s) and 8,8 (1H, s).
