A solution of 4-(4-morpholinyl)benzonitrile (930 mg, 5.00 mmol) in 1:1 dioxane:water (20 mL) was treated with potassium hydroxide (1.12 g, 20 mmol). The mixture was heated at reflux for 96 h, concentrated, and the residue was dissolved in water. Upon acidification (pH ˜2-3), a white precipitate resulted which was collected by filtration yielding 1.21 g (99%) of the title compound.
