Reaction Steps

A 2 M aqueous sodium hydroxide solution (1.0 mL) was added at room temperature to a methanol (4 mL) solution of methyl 6-(1-((6-cyclopropyl-3-ethoxy-2,4′-difluorobiphenyl-4-yl)methyl)piperidin-4-yl)-2-methyl-5-oxo-5,6,7,8-tetrahydro-1,6-naphthyridine-3-carboxylate (460 mg), and the mixture was stirred at 50° C. for 30 minutes. The reaction mixture was neutralized with hydrochloric acid at room temperature and then stirred at room temperature for 2 hours, and then, the deposited solid was collected by filtration. The obtained solid was recrystallized (DMSO/ethanol/water) to obtain the title compound (385 mg).
