Yield: 98%
Reaction Conditions:
in toluene for 48 h;Heating / reflux;
Steps:
39.4
Step 4: A mixture of benzofuran-3(2H)-one (1.34 g, 10 mmol) and (carboxymethylene)triphenylphosphorane (5.22 g, 15 mmol) was refluxed in toluene (100 ml) for 48 hrs. At the end, the reaction mixture was concentrated and loaded over a silica-gel column. The column was eluted with hexane (500 ml) and then with 25% ethyl acetate. The product, ethyl(-1-benzofuran-3-yl)acetate was obtained as a white oil. Yield: 2.0 g (98%); (M+H): 205.
