Addition of water with ethylacetate, washing of the organic phase with saturated NaHCO3, NaCl, drying over Na2SO4 and flash chromatography (silica gel, CH2Cl2/MeOH 95:5) gave 8-(3,4-dichlorobenzyl)-7-(3-fluoropyrrolidin-1-yl)-5,6,7,8-tetrahydronaphthalen-2-ol (330 mg, 39%). The ethylene sulfonamide side chain was added in analogy to examples 1, 7, 8 to give 1-cyclopropyl-N-[2-({8-(3,4-dichlorobenzyl)-7-[3-fluoropyrrolidin-1-yl]-5,6,7,8-tetrahydronaphthalen-2-yl}oxy)ethyl]methanesulfonamide.
