Sodium carbonate solution was then added until the pH was 11 and the stirring continued overnight. A small amount of sodium hydroxide solution was added to give a pH of 12, followed three hours later by a small quantity of Aliquat 336 (trademark, tricaprylylmethylammonium chloride), and after 2 hours the reaction was complete. A dichloromethane extract was washed (water and brine), dried (sodium sulfate) and evaporated to give the title compound.
