Procedure

A 2 M aqueous sodium hydroxide solution (2 mL) was added at room temperature to an ethanol (8 mL) solution of methyl 6-(1-((6-cyclopropyl-2,4′-difluoro-3-methoxybiphenyl-4-yl)methyl)piperidin-4-yl)-5-oxo-2-propyl-5,6,7,8-tetrahydro-1,6-naphthyridine-3-carboxylate (335 mg), and the mixture was stirred at 80° C. for 3 hours in a nitrogen atmosphere. Then, the solvent was distilled off under reduced pressure. Water was added to the obtained residue, and the mixture was neutralized with 2 M hydrochloric acid. The deposited crystals were collected by filtration and dissolved in ethanol, and then, the solvent was distilled off under reduced pressure. The obtained residue was crystallized (hexane/ethyl acetate) and further recrystallized (hexane/ethanol) to obtain the title compound (276 mg).
