Методика
To a solution of thioacetic acid S-(2-trifluoromethyl-benzyl)ester (10.2 g, 37.5 mmol) in methanol (130 ml) potassium carbonate (5.18 g, 37.5 mmol) was added at room temperature and it was stirred for 30 min. 3-Bromomethyl-pyridine-2-carboxylic acid methyl ester (4.40 g, 18.7 mmol) was added and after refluxing for 150 min the solution was diluted with water, extracted with ethylacetate, the organic phase dried with sodium sulfate and concentrated. Chromatography over silica with ethylacetate/cyclohexane gave 7.82 g colorless crystals (18.7 mmol).
