実験手順

Ethyl [4-(chloromethyl)-2-methylphenoxy]acetate (35.9 g, 0.148 mols) was dissolved in dry acetonitrile (285 mL). Sodium iodide (20.1 g, 0.135 mols 1 eq) was added in one portion and mixture stirred for 5 mins. A solution of the N-butyl-N-(2,4′-dimethyl-1,1′-biphenyl-3-yl)amine (34 g. 0.135 mol) and disopropylethylamine (23.5 mL, 0.135 mol) in dry acetonitrile (285 mL) was added over 10 min and cooling applied to maintain reaction temperature at ca. 16° C. during the addition. The reaction was concentrated in vacuo and the resultant orange oil partitioned between DCM (700 mL) and water (700 mL). The aqueous was extracted with DCM (500 mL) and the combined organic extracts were cautiously washed with brine (300 mL). After drying (Na2SO4) the mixture was concentrated in vacuo to give a dark orange oil. Purification using flash chromatography on (2 kg silica column), eluting with 1:1–0:1 cyclohexane:DCM afforded the title compound as a yellow oil (48.8 g).
