실험 절차

To a solution of 5-acetyl-2-((2R,6S)-2,6-dimethyl-morpholin-4-yl)-3,4-difluoro-benzaldehyde (Intermediate 11, 3.0 g, 9.17 mmol) in IPA was added barbituric acid (1.4 g, 11.00 mmol), and the mixture was heated at 85° C. for 12 hours. Solvents were evaporated and the residue was purified over neutral alumina using a gradient of methanol in CH2Cl2 to give the title compound as a racemic mixture in the form of an off-white solid. Yield: 3.0 g (75%).
