Reaction Steps
To a solution of methyl 6-fluoro-1-oxo-1,2-dihydroisoquinoline-4-carboxylate (1.3 g) in methanol (3 ml) was added a aqueous solution (3 ml) of sodium hydroxide (1 g) and the reaction mixture was heated at 80° C. for 3 h. The reaction was cooled to 20° C. and carefully acidified with concentrated hydrochloric acid. The white precipitate was isolated by filtration, washed with water and methanol to yield the title compound (1.16 g)
