반응 단계
A mixture of para formaldehyde (105.0 g), N,N-diethyl amine (300 g) and copper(II) acetate (7.5 g) in 1,4 dioxane (900 ml) was heated to 60-65° C. After 1.5 h, 2-propyne-1-ol (150 g, 2.7 moles) was added and the mixture was heated at 90-95° C. after 2 hrs; excess solvent, 1,4 dioxane, evaporated at reduced pressure to afford 315 g (84%) of the product as an oil.
