実験手順

Prepared according to Rubinsztajn et al. Tetrahedron Lett. 1992, 33, 14, 1821-1824. To a solution of 4-ethynyl-3-methylpyridine (420 mg, 3.58 mmol) in DCM (10 mL) at 0° C. was added methyl triflate (450 μL, 3.94 mmol), drop-wise. After stirring for 30 min at 0° C., ether was added and the precipitate was collected and dried, affording the title compound (863 mg, 86%) as a light brown solid.
