A mixture of 1-(7-chloroquinol-4-yl)-5-methoxy-2-methylindolin-3-ylacetic acid (1g.) and 2,3,5,6-tetrachloro-1,4-benzoquinone (1g.) in dry xylene (50ml.) was refluxed for 2 hours. The solvent was removed in vacuo and the residue adsorbed on a column of chromatographic silica gel (50g.). The column was eluted with chloroform containing increasing amounts of methanol (starting with pure chloroform, and then using increments of 1% v/v of methanol in chloroform; product mainly eluted with 5% methanol in chloroform) to give 1-(7-chloroquinol-4-yl)-5-methoxy-2-methylindol-3-ylacetic acid, m.p. 248°-250° C.
