Reaction Steps

A solution of 4-bromo-2-fluorobiphenyl (38.1 gram) in tetrahydrofuran (60 ml) was added over 20 minutes to magnesium turnings (4 gram) suspended in tetrahydrofuran (20 ml), reaction being initiated by adding a crystal of iodine and warming as usual. This Grignard reagent was now added to a solution of trans-4-propylcyclohexylacetyl chloride (40 gram) and cuprous chloride (0.4 gram) in tetrahydrofuran (200 ml) with stirring at -60° C. over 90 minutes. After allowing to warm to room temperature over two hours, the mixture was decomposed with water and the product extracted with petroleum ether (bpt. 60°-80°). The crude material was recrystallized twice from ethanol at 5° C. to give the product (20.6 gram, 40% theory), m.p. 96.5°-97.3° C., which was found to be 99.6 pure by glc.
