Reaction Steps

To a solution of 2-{3-[4-(4-Ethyl-2-hydroxy-phenoxy)-3-fluoro-phenoxy]-propyl}-isoindole-1,3-dione (0.096 mmol; 42 mg) in methanol (2 mL), under argon, was added hydrazine monohydrate (0.21 mmol; 10 μL). The reaction was heated to reflux for 1 h 30. After cooling to 0° C., the mixture was hydrolysed with HCl 1N and filtered. The filtrate was basified with NaOH 0.1 N (pH=11) and extracted with chloroform (3*5 ml). Combined organic phases were dried over Na2SO4, concentrated in vacuo. The title compound (13 mg; 0.04 mmol; 44%) was obtained as yellow oil, after purification by preparative TLC (dichloromethane/methanol/NH4OH: 90/10/1).
