Reaction Steps

To a solution of 3-(2-Trifluoromethyl-phenylmethanesulfonylmethyl)-pyridine-2-carboxylic acid methyl ester (7.58 g, 19.6 mmol) in tetrahydrofurane (160 ml) potassium tert-butoxide (2.20 g, 19.57 mmol) was added at room temperature and stirring was continued for 3.5 h. 1M HCl was added, diluted with methylenehloride and extracted. The organic phase was dried with sodiumsulfate and concentrated. Chromatography over silica with ethylacetate/cyclohexane gave 2.50 g colourless crystals (7.32 mmol).
