Procedure
The title compound was prepared in accordance with the general method of Example 1, from 2-bromo-6-(fluoromethyl)pyridine (336 mg, 1.77 mmol, Example 190(E)) and 2-(but-3-ynyl)isoindoline-1,3-dione (320 mg, 1.61 mmol). The crude residue was purified by flash chromatography (cyclohexane/AcOEt 75:25) to yield 320 mg (1.04 mmol, 65%) of 2-(4-(6-(fluoromethyl)pyridin-2-yl)but-3-ynyl)isoindoline-1,3-dione as a white solid.
