1-(2-Methoxyphenyl)piperazine → HCID 70619596, compound

Participants

Reaction Steps

A solution of 13.1 g of 6,7-epoxy-5,6,7,8-tetrahydro-1,4-diacetoxynaphthalene and 29.8 g of 1-(o-methoxyphenyl)-piperazine in 200 ml of xylene is refluxed under nitrogen for 48 hours. The reaction mixture is then cooled, the crystalline precipitate filtered, washed with ether, and dried in vacuo to afford 10.55 g of crude crystalline product. Recrystallization of 7.50 g of this material from ethyl acetate/ethanol gives 4.0 g of the title compound, melting point 222°-224° C.
