Reaction Steps
To a solution of ethyl 4-[7-chloro-4-(4-fluorophenyl)-2-methylpyrrolo[1,2-b]pyridazin-3-yl]-3-hydroxybutanoate (52 mg) in tetrahydrofuran (1 ml) was added 1N sodium hydroxide (0.27 ml), followed by methanol (1 ml). After standing at 20° C. overnight, the mixture was partitioned between 1N hydrochloric acid and ethyl acetate. The organic layer was separated, washed with water and brine, dried over magnesium sulfate, and evaporated to give 4-[7-chloro-4-(4-fluorophenyl)-2-methylpyrrolo[1,2-b]pyridazin-3-yl]-3-hydroxybutanoic acid (45 mg) as an yellow oil.
