    • Methylthio group of quinolinone 1a was removed by Raney nickel to provide 3-acyl-4-quinolinone (8) and acyl group of 1a was removed by treatment with trifluoro acetic acid as solvent to give 2-methylthio-4-quinolinone (9). Reaction of 8 or 9 with MSH did not proceed after overnight stirring under the same condition.
