Procedure

To a solution of 0.30 g of tert-butyl((7-oxo-5,6,7,8-tetrahydro-1,8-naphthyridin-2-yl)methyl)(1-(trifluoroacetyl)piperidin-4-yl)carbamate in 12 mL of methanol, 0.10 g of potassium carbonate and 3 mL of water were added, and the mixture was stirred at room temperature for 7 hours 30 minutes. To the reaction mixture, water, a saturated aqueous sodium hydrogen carbonate solution and chloroform were added, the organic layer was separated, and the aqueous layer was added with sodium chloride and extracted with chloroform. The organic layer and the extract were combined, the resultant solution was washed with a saturated aqueous sodium chloride solution and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure to obtain 0.24 g of tert-butyl((7-oxo-5,6,7,8-tetrahydro-1,8-naphthyridin-2-yl)methyl)(piperidin-4-yl)carbamate as a colorless foam.
