To a solution of ethyl 4-(4-cyanophenyl)-2-(2-ethoxy-2-oxoethyl)-7-ethylpyrrolo[1,2-b]pyridazine-3-carboxylate (77.9 mg) in ethanol (0.5 mL)-tetrahydrofuran (0.5 mL) was added 1N potassium hydroxide. The resulting solution was stirred for 25 hours at room temperature. The mixture was stirred for futher 1 hour after adding 1N potassium hydroxide (0.04 mL). The reaction was quenched by adding 1N hydrochloric acid (0.23 mL). The volatile was evaporated off, and the resulting residue was partitioned between ethyl acetate (10 mL) and 1N hydrochloric acid (6 mL). The organic layer was washed with brine, dried, and evaporated to give [4-(4-cyanophenyl)-3-(ethoxycarbonyl)-7-ethylpyrrolo[1,2-b]pyridazin-2-yl]acetic acid as an yellow solid (67.7 mg, 93.4%).
