Reaction Steps

To a solution of 3-(7-ethyl-2-neopentylpyrrolo[1,2-b]pyridazin-4-yl)benzamide (35 mg) in ethanol (1 mL) was added water (0.2 mL) and potassium hydroxide (68.9 mg) at ambient temperature. The reaction mixture was heated at 60° C. After 2 hours, potassium hydroxide (100 mg) was added. After 5 hours, potassium hydroxide (100 mg) was added. After 12 hours, the mixture was acidified with 1N hydrogen chloride. The precipitate was filtered, washed with water and ethyl acetate to give 3-(7-ethyl-2-neopentylpyrrolo-[1,2-b]pyridazin-4-yl)benzoic acid as an yellow solid (19 mg, 54.1%).
