実験手順

To a solution of 1-{2-[(3R,4S)-4-({[5-chloro-6-(hydroxymethyl)-3-pyridinyl]methyl}amino)-3-hydroxy-1-piperidinyl]ethyl}-7-fluoro-1,5-naphthyridin-2(1H)-one (Example 3: 19.5 mg, 0.042 mmol) in DCM (2 ml) at 0° C. was added HCl (4M in 1,4-dioxane) (10.64 μl, 0.043 mmol). The reaction mixture was stirred at RT for 30 min, the solvent was evaporated under vacuum and the crude was dispersed in hexane/DCM. The precipitated solid was isolated by filtration under vacuum and washed with DCM and hexane. The obtained solid was dried overnight at 40° C. under vacuum to give 1-{2-[(3R,4S)-4-({[5-chloro-6-(hydroxymethyl)-3-pyridinyl]methyl}amino)-3-hydroxy-1-piperidinyl]ethyl}-7-fluoro-1,5-naphthyridin-2(1H)-one hydrochloride (19.5 mg, 0.039 mmol, 92% yield) as a white solid.
