Reaction Steps

70 mg diethyl {[(3,5-dichloro-phenylsulphonyl)-(1-pyrimidin-2-yl-2,3-dihydro-1H-indol-5-yl)-amino]-methyl}-phosphonate are dissolved in 3 ml dichloromethane. Under argon 200 μl trimethylsilylbromide are added thereto and the mixture is refluxed for 2 hours. After cooling to ambient temperature 1 ml of methanol is added and the mixture is stirred for a further 1 hour. Then the solvents are eliminated in vacuo. The residue is taken up in 3 ml of methanol, stirred for 10 minutes and the solvent is eliminated in vacuo. The residue thus obtained is extracted from dichloromethane with 1% methanol. The solid is suction filtered and dried.
