Potassium Carbonate → HCID 59678709, compound

Participants

Reaction Steps

Following the same procedure as in Example 2, 15.4 g (0.1 mole) of 1-hydroxy-3,4-dimethoxybenzene, 13.8 g (0.1mole) of anhydrous potassium carbonate in ml 50 of acetone and 13.3 g (0.1 mole) of 1-bromo-2-butyne were reacted. After work up and evaporation of the mixture u.v. (20° C./21 mbar), a residue was obtained, that after purification on silica gel column (eluant n-hexane:ethyl acetate 5:1 v/v) gave a thick oil that after some time solidified with low melting point (28-30° C.), whose NMR and MS analyses corresponded to those of the aforementioned compound.
