Participants

Reaction Steps

1-[4-(4-fluorobenzyloxy)-3-isobutylbenzoyl]-4-isobutylpiperazine (1.01 g) was dissolved in diethyl ether (10 ml) and then 10 ml of a diethyl ether solution containing oxalic acid (0.4 g) was added thereto. After this mixture was stirred for 10 minutes at room temperature, the resulting crystals were collected by filtration and then recrystallized (from n-hexane/ethanol), thereby yielding 0.93 g of the aimed compound.
