Reaction Steps
Sodium hydroxide (50% aqueous solution, 29.3 g, 0.505 mol) was added to a mixture of 4-bromo-benzeneacetonitrile (9.80 g, 0.0500 mol), benzyltriethylammonium chloride (0.90 g, 0.0040 mol), ethane, and 1-bromo-2-chloro-(14.5 g, 0.101 mol) at 50° C. overnight. The mixture was poured into ice-water (80 mL) and was extracted with ethyl ether (4×50 mL). The combined organic phase was washed with HCl aqueous solution (1N, 20 mL) and brine (2×30 mL) successively, dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue was the desired product, which was directly used in the next step without further purification.
