To 0.102 g (0.36 mmol) of the above prepared [2-(3-methoxy-propyl)-4-methylamino-phenoxy]-acetic acid ethyl ester, dissolved in 1.4 ml of abs. DMF, were added successively at 0° C. 0.017 g of NaH (60% in mineral oil, 1.2 eq.), 0.054 g (1 eq.) of NaI and 0.100 g (1 eq.) of 3-chloromethyl-2-methyl-6-(4-trifluoromethyl-phenyl)-pyridine (see below 1K]). The reaction was allowed to proceed for 5 Min. at 0° C. and for 0.5 h at ambient temperature. Pouring onto crashed ice/KHSO4, twofold extraction with AcOEt, washing with water and brine, drying over magnesium sulfate, and evaporation of the solvents, followed by flash chromatography (SiO2, hexane/AcOEt=75/25), yielded 0.126 g of the title compound as light yellow oil.
