Reaction Steps

A solution of NaOH in water (2 ml, 50%) was added to a mixture of quinolin-4-ylacetonitrile (0.5 g, 0.002 mol), 1-bromo-2-chloro-ethane (1.0 mL, 0.012 mol), and benzyltriethylammonium chloride (0.1 g, 0.0004 mol) at 50° C. After the mixture was stirred at 50° C. for 3 hours, 1,2-ethanediol (5 mL, 0.09 mol) was added. Then the reaction mixture was stirred at 100° C. overnight. The reaction mixture was cooled to room temperature and washed with ether (3×). The aqueous layer was acidified (pH=2), and then extracted with ethyl acetate (3×). The combined organic layer was dried over MgSO4, filtered, and concentrated to afford the desired product. LC/MS: 214.1 (M+H+).
