Reaction Steps

Prepared according to Rubinsztajn et al. Tetrahedron Lett. 1992, 33, 14, 1821-1824. To a suspension of 4-ethynylpyridine hydrochloride (500 mg, 3.58 mmol) in DCM (50 mL) at 0° C. was slowly added NaHCO3 solution (aq, satd, 10 mL). After stirring for 5 min, the layers were separated and the aqueous was extracted with DCM (2×10 mL). The combined organic layers were dried over Na2SO4, concentrated in vacuo and subjected to high vacuum for 10 min. The crude residue was dissolved in DCM (10 mL), cooled to 0° C. and methyl triflate (450 μL, 3.94 mmol) was added drop-wise. After stirring for 30 min at 0° C., ether was added and the precipitate was collected and dried, affording the title compound (870 mg, 91%) as a light brown solid. Analytical data was identical to literature reported values.
