A mixture of 2-(4-octyloxy-phenyl)-morpholine (1.99 g; 6.8 mmol), 2-(2-chloroethoxy)-tetrahydro-2H-pyran (1.21 ml; 8.2 mmol), K2CO3 (1.89 g; 13.7 mmol) and NaI (0.20 g; 1.4 mmol) in DMF (15 mL) was heated to 100° C. overnight. After cooling to RT the reaction mixture was partitioned between 5% aqueous NaHCO3 solution and Et2O. The organic layer was dried (Na2SO4), filtered, and concentrated in vacuo. The residue was purified by column chromatography (SiO2, EtOAc) to afford 2-(4-octyloxy-phenyl)-4-[2-(tetrahydro-pyran-2-yloxy)-ethyl]-morpholine (2.04 g).
