Reaction Steps

Zinc trifluoromethanesulfonate (2.378 mmol, 0.864 g), 2-methyl-3-butyn-2-ol (11.89 mmol, 1 g) and triethylamine (17.83 mmol, 1.804 g) were added into a flask under nitrogen atmosphere. Ethyl diazoacetate (14.27 mmol, 1.628 g) was added slowly and the temperature was carefully raised to 100° C. and stirred for 8 h. Water was added and the mixture was extracted twice with DCM. The combined DCM phases were dried, filtered and evaporated. The crude product was purified by flash chromatography. 0.658 g of the title compound was obtained. 1H-NMR (400 MHz, DMSO-d6): δ 1.28 (t, 3H), 1.45 (s, 6H), 4.24 (q, 2H), 5.34 (s, 1H), 6.52 (s, 1H), 13.22 (bs, 1H).
