Reaction Steps

To a solution of 2.0 g (18 mmol) of 1-(trimethylsilyl)-1-proyne in toluene (20 mL) was added 2.3 g (18 mmol) of ethyl azido-acetate. The reaction mixture was heated at 120° C. overnight then cooled to ambient temperature. All volatiles were removed under reduced pressure and the residue was purified by column chromatography on silica gel eluting with a 5-25% acetone in hexanes gradient to yield the title compound as a colorless oil (0.77 g, 18%). 1HNMR (500 MHz, CDCl3): δ 5.01 (s, 2H), 4.2 (m, 2H), 2.25 (s, 3H), 1.22 (m, 3H), 0.295 (s, 9H).
