To a solution of 5-[4-acetyl-2,5-dimethyl-1-(4-ethoxyphenyl)-1H-pyrrol-3-yl]-5-oxo-pentanoic acid methyl ester (250 mg, 0.65 mmol) in ethanol (1 mL) was added a 1.0M solution of hydrazine in ethanol (0.72 mL, 0.72 mmol). The solution was stirred overnight at rt and concentrated in vacuo to give 4-[6-(4-ethoxyphenyl)-4,5,7-trimethyl-6H-pyrrolo[3,4-d]pyridazin-1-yl]-butyric acid methyl ester as a white solid: 1H NMR (CDCl3, 500 MHz) δ 7.11-7.08 (m, 2H), 7.05-7.03 (in, 2H), 4.11 (q, 2H), 3.63 (s, 3H), 3.12 (t, 2H), 2.77 (s, 3H), 2.51 (t, 2H), 2.41 (s, 3H), 2.40 (s, 3H), 2.14 (quintet, 2H), 1.47 (t, 3H); MS (ESI) 382 (M+H)+.
