Procedure

The title compound was prepared in accordance with the general method of Example 1, from 2-bromo-pyridine (137 mg, 0.86 mmol) and (3-fluoro-phenyl)-pent-4-ynoyl-carbamic acid tert-butyl ester (250 mg, 0.86 mmol). Reaction time: 3 hours. The crude residue was purified by flash chromatography (cyclohexane/AcOEt 4:1) to yield 190 mg (0.52 mmol, 60%) of (3-fluoro-phenyl)-(5-pyridin-2-yl-pent-4-ynoyl)-carbamic acid tert-butyl ester as a white solid.
