Procedure: 166 mg (1.017 mmol) of 5-hydroxy-3,4-dihydroisoquinolin-1(2H)-one, 289 mg (1.068 mmol) of 1-(bromomethyl)-4-[(trifluoromethyl)sulphanyl]benzene and 365 mg (2.645 mmol) were suspended in 3 ml of ethanol and stirred under reflux for 6 h. After cooling, the insoluble constituents were filtered off and the solvent was removed under reduced pressure. The residue was dissolved in chloroform and water. The phases were separated, the organic phase was dried over sodium sulphate and the solvent was removed under reduced pressure. The crude product was purified by chromatography (ethyl acetate:n-heptane 2:1). This gave 200 mg (54% of theory) of the desired 5-({4-[(trifluoromethyl)sulphanyl]benzyl}oxy)-3,4-dihydroisoquinolin-1(2H)-one. 1H-NMR (400 MHz, d6-DMSO δ, ppm) 7.89 (br. s, 1H), 7.52-7.44 (m, 4H), 7.28 (t, 1H), 7.22 (d, 1H), 5.16 (s, 2H), 3.33 (dt, 2H), 2.84 (t, 2H). under reflux for 6 h After cooling the insoluble constituents were filtered off the solvent was removed under reduced pressure The residue was dissolved in chloroform The phases were separated the organic phase was dried over sodium sulphate the solvent was removed under reduced pressure The crude product was purified by chromatography (ethyl acetate:n-heptane 2:1)

The resulting mixture was stirred at room temperature overnight. The reaction mixture was quenched with water, extracted with EtOAc, and dried over Na2SO4. The crude product was purified by silica gel chromatography (10%-40% EtOAc/hexanes) to yield the title compound as a brown solid.
