Procedure
0.46 g (0.76 mmol) of crude 3-[4-(1-methanesulfonylimino-1-methylsulfanyl-methyl)-piperazin-1-ylmethyl]-2-phenyl-quinoline-4-carboxylic acid ((S)-1-cyclohexyl-ethyl)-amide (compound of Description 16) and 5 ml of pyrrolidine were heated to reflux for 5 h. The excess of pyrrolidine was removed in vacuo and the residue was purified by flash chromatography on silicagel (CH2Cl2/MeOH: 97/3). After concentration of the desired fractions, the residue was crystallised in di-isopropyl ether to afford 0.310 g (yield 65%) of the title compound as white crystals.
