A solution of 466 mg (1 mmol) of N-[4-(4-Bromo-butoxy)-phenyl]-N-methyl-4-trifluoromethyl-benzenesulfonamide 69-9844 in 3.5 ml DMA was treated at 0° C. with 0.195 ml (2 mmol) of 2-ethylaminoethanol and stirred at RT for 15 h. The reaction mixture was cooled (0° C.) again, treated with 0.195 ml (2 mmol) of 2-ethylaminoethanol and stirred at RT for further 24 h. The solution was concentrated, the residual oil was dissolved in water/acetontrile 1:1/5% formic acid and purified by prep. HPLC: RP-18, acetonitrile/water, 10%-60% acetonitrile. The pure fractions were collected, dissolved in EtOAc, washed with aqueous sat. NaHCO3 solution, and the organic phase was dried (Na2SO4) and evaporated to yield 360 mg (76%) of N-(4-{4-[Ethyl-(2-hydroxy-ethyl)-amino]-butoxy}-phenyl)-N-methyl-4-trifluoromethyl-benzenesulfonamide, MS: 475 (MH+).
