4.2 g of ethyl 3-(2-(4-toluenesulphonylamino)indan-5-yl)-3-(3-pyridyl)-prop-2-enoate are refluxed for 30 minutes in 40 ml of ethanol and 1.5 ml of 15N sodium hydroxide solution. Then the cooled solution is washed 3 times with 50 ml of methylene chloride and then acidified. The precipitate formed is washed, dried and then recrystallised from n-butanol.
