Procedure

3-[6-(t-Butyldimethylsilanyloxymethyl)pyridin-2-yl]-propionic acid (1.65 g) was dissolved in 20 mL of methylene chloride, and 584 μL of morpholine, 1.6 g of WSC and 1.56 mL of triethylamine were added to the solution, and then the mixture was stirred at room temperature overnight. The reaction mixture was diluted with chloroform, transferred into a separating funnel, and washed with water. The organic layer was dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by chromatography on silica gel (chloroform-methanol=30:1) to give 1.91 g of 3-[6-(t-butyldimethylsilanyloxymethyl)pyridin-2-yl]-1-morpholin-4-yl-propan-1-one as a yellow oil.
