Reaction Steps

Ethyl chlorooximidoacetate (4 g, 26.4 mmol) and 4-pentyn-2-ol (10.00 ml, 107 mmol) were dissolved in diethyl ether (30 ml). A solution of triethylamine (3.68 ml, 26.4 mmol) in diethylether (20 ml) was added dropwise to the reaction mixture. After 1 h of stirring at RT the reaction mixture was washed with brine and water, dried with MgSO4 and evaporated to dryness. The residue was purified with flash chromatography using a gradient of methanol in methylene chloride affording 2.51 g (48%) of the title compound. 1H-NMR (400 MHz; d6-DMSO): δ, 1.11 (d, 3H), 1.31 (t, 3H), 2.82-2.94 (m, 2H), 3.93-4.03 (m, 1H) 4.35 (q, 2H), 4.89 (d, 1H), 6.67 (s, 1H).
