A series of prazosinanalogues comprised of N-acyl derivatives of N'-(4-amino-6,7-dimethoxyquinazolin-2-yl)piperazine was prepared and the nature of their binding to alpha 1-adrenoceptors was investigated. Derivatives with alpha, beta-unsaturated acyclic acyls had some affinity but no irreversible action at the receptor. Other potent compounds, also without irreversible activity, contained cinnamoyl
