Reaction Steps

0.7 g of lithium and 5.7 g of ZnBr2 are added at 0° to a mixture of 15.4 g of trans-4-pentylcyclohexylethyliodide and 100 ml of THF/toluene (1:4), and the reaction mixture is treated with ultrasound at 0°-10° for 4 hours. 14.8 g of 4-trifluoromethoxybromobenzene and 0.88 g of PdCl2 (dppf) are subsequently added at 5°. The mixture is allowed to warm to room temperature and is stirred for a further 16 hours. The mixture is then poured into 100 ml of saturated NH4Cl solution, and the organic phase is worked up. After purification by chromatography and/or crystallization, 1-(4-trifluoromethoxyphenyl)-2-(trans-4-pentylcyclohexyl)-ethane is obtained.
