実験手順
Add 2-chloropyridine (1 g, 8.8 mmole) to a mixture of n-butyl lithium (1.6 M in hexane) (22 mL, 35.2 mmole) and 2-dimethylamino-ethanol (1.56 g, 17.6 mmole) in hexane (20 mL at −78° C.) and stirred for 1 hour. Then add 1-methyl-piperidine-4-carboxylic acid methoxy-methyl-amide (3.2 g, 17.6 mmole) in hexane (5 mL) and stir the mixture for 1 hour. Quench the reaction mixture with water and extract twice with ethyl acetate, dry the organic layer with anhydrous sodium sulfate, evaporate the solvent and purify the residual product by chromatography on a silica gel column to give about 1 g of the title product.
