Reaction Steps
Pyrrolidine (20 ml) was added to 2-bromomethyl-5-formylamino-2,4,6,7-tetramethyl-2,3-dihydrobenzofuran (3.0 g, 9.6 mmol) and the mixture was heated at 160° C. in an autoclave for 15 hours. After the reaction mixture was cooled, the mixture was diluted with water and the product was extracted with ethylacetate. The extract was washed with water and dried and then the solvent was distilled off. The residue was purified by column chromatography on silica gel (chloroform-methanol, 9:1) and recrystallized from hexane to obtain the desired compound (2.2 g, yield: 83.5%), m.p. 85°-86° C. (dec.).
