Procedure: A solution of 3-phenylsulfonyl-8-piperazin-1-yl-quinoline (D12) (200 mg, 0.55 mmol) in dry THF (2 ml) was treated with sodium hydride (24 mg, 0.6 mmol, 60% oil dispersion), and 1-bromo-2,2,2-trifluoroethane (815 mg, 5 mmol). The mixture was heated to 100° C. for 4 days then cooled, evaporated and the residue subjected to purification by flash chromatography on silica gel (eluting with dichloromethane-methanol-aq. NH3) to give the free base form of the title compound. This was treated with 1M HCl in ether then crystallised from isopropanol to give the title compound (E8) as a yellow solid: then cooled evaporated the residue subjected to purification by flash chromatography on silica gel (eluting with dichloromethane-methanol-aq.
