Sodium Hydroxide → HCID 19018767, compound

Participants

Reaction Steps

1 g (3.7 mM) of N-formyl-N'-[2-(2-thienylmethylthio)ethyl]piperazine was dissolved in 10 ml of methanol. Thereto was added a solution of 178 mg (4.4 mM) of sodium hydroxide in 10 ml of water. The mixture was refluxed for 10 hours with heating, to give rise to a reaction After the completion of the reaction, the solvent was removed under reduced pressure. The residue was subjected to extraction with chloroform. The extract was washed with water and a saturated aqueous sodium chloride solution in this order and dried over anhydrous sodium sulfate. The solvent was removed by distillation. The residue was purified by silica gel chromatography to obtain 800 mg of N-[2-(2-thienylmethylthio)ethyl]piperazine at a yield of 89%.
