الإجراء التجريبي

A suspension of 2,4-dimethyl-6-oxo-1-phenyl-1,6-dihydro-pyridine-3-carboxylic acid [(S)-cyclobutyl-(3-fluoro-phenyl)-methyl]-amide (9.91 mg, 0.0245 mmol and selectfluor (10.0 mg, 0.0282 mmol) in acetonitrile (0.1 mL) was sonicated for 3 hrs at 40° C. then allowed to stand for 3 days. It was quenched with water (3 ml) and extracted with ethyl acetate (3×1 mL). The combined organic solution was transferred to a preparative TLC plate (SiO2, 0.25 mm×20 cm×20 cm) and eluted with ethyl acetate to give the crude title product (4 mg, 19% yield). LC-MS (m/z) 423.2 (MH+); tR=1.44.
