Procedure

To a stirred solution of tert-butyl 3-(2-{2-(cyclopropylmethoxy)-6-[(4-methoxybenzyl)oxy]phenyl}-7-oxo-7,8-dihydro-1,8-naphthyridin-4-yl)-1-piperidine-carboxylate (0.260 g, 0.425 mmol) in 1,4-dioxane (2 mL) was added 4 N HCl in dioxane (2 mL). The mixture was stirred at room temperature overnight, and diluted with ethyl acetate. The resulting precipitate was collected by filtration, washed with ethanol, and dried under reduced pressure to give 7-[2-(cyclopropylmethoxy)-6-hydroxyphenyl]-5-(3-piperidinyl)-1,8-naphthyridin-2(1H)-one hydrochloride as a yellow solid (0.146 g, 80%).
