ESI MS: m/z = 638.0 [M+H]+ (100 %). General method for the preparation of arylpiperazine derivatives of 19-(4-bromobutyl)-1,16-diphenyl-19-azahexacyclo[14.5.1.02,15.03,8.09,14.017,21]docosa-2,3,5,7,8,9,11,13,14-nonaene-18,20,22-trione

(3–9) A mixture of derivative (2) (0.3 g, 0.002 mol) and the corresponding amine (0.004 mol), anhydrous K2CO3 (0.3 g), and catalytic amount of KI were refluxed in acetonitrile for 30 h. Then the mixture was filtered off and the solvent was evaporated. The gray residue was purified by column chromatography (chloroform:methanol 9.5:0.5 vol) and/or crystallized from methanol. Obtained compounds were converted into their hydrochlorides. The solid product was dissolved in methanol saturated with gaseous HCl. The hydrochloride was precipitated by addition of diethyl ether.
