Participants

Reaction Steps

The crude indoline 9 was dissolved in acetic anhydride (35 ml). This solution was stirred for 1 h at room temperature. Thereupon the acetic anhydride was removed in vacuo. The residue (~27 g) was sufficiently pure for further conversions. A sample of this residue was purified by flash column chromatography (SiO2, CH2Cl2 /acetone 95/5). A pale yellow oily product was obtained.
