Reaction Steps

To a solution of 3.3 g (0.01 mole) of 1-[4,4-bis(p-fluorophenyl)butyl]piperazine in 10 ml of CHCl3 was added dropwise over a period of 15 minutes 1.2 g (0.011 mole) of ethyl chloroformate in 10 ml of CHCl3. The mixture was refluxed for 2 hours and was made basic with 0.8 g of sodium hydroxide in 25 ml of water.
