PROCEDURE

实验过程

1.68 g of 2-butyl-3-(4-hydroxybenzoyl)-5-hydroxymethyl-1-benzofuran, 1.18 g of 1-chloro-3-(dibutylamino)propane and 0.960 g of potassium carbonate are dissolved in 70 ml of methyl ethyl ketone. The mixture is brought to reflux for 6 hours, water is added and separation is carried out by settling. Extraction with ethyl acetate and washing with a saturated sodium chloride solution are carried out. Purification is subsequently carried out by chromatography on silica (eluent: 95/5 dichloromethane/methanol), which gives the desired compound in the free base form.
