Reaction Steps

To a solution of 0.29 g of 1-formyl-4-isopropylpiperazine in 10 ml of methanol were added 0.5 ml of hydrochloric acid and 1 ml of water and the mixture was heated under reflux for 2 hours. The reaction solution was distilled off under reduced pressure, a iN aqueous solution of sodium hydroxide was added and the mixture was extracted with chloroform and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure to afford 0.1 g of the title compound.
