Procedure

To a solution of 1-(5-Bromo-pyridin-2-yl)-2,2,2-trifluoro-ethanone (7.5 g, 29.52 mmol) in dry toluene (30 mL) is added bezylamine (3.15 g, 29.52 mmol) and titanium ethoxide (7.4 g, 32.48 mmol) at room temperature then stir for 3 hours. Reaction mixture is diluted with saturated sodium bicarbonate solution and extracted with ethyl acetate. Organic layer is dried over sodium sulphate, solvent is evaporated in vacuo and purified by column chromatography eluting in 20% ethyl acetate in hexane to afford the title compound (0.45 g). LC-MS (m/z): [M+H]=345.0.
