A compound represented by the formula (I) :
where A is a phenyl group substituted at least with a nitro group ; B is a group represented by the formula :
[where R1 and R2 are, the same or different, a lower alkyl group or a benzyl group which may be substituted with a halogen atom, or they may be combined, together with the adjacent nitrogen atom, through or not through an oxygen atom to form a six-membered ring or through a nitrogen atom to form a group represented by the formula :
(where R3 is a lower alkyl group, a phenyl or benzyl group which may be substituted with a halogen atom, or a diphenylmethyl group)] ; and R is a hydrogen atom or a lower alkyl group ,or a salt thereof. This compound or a salt thereof is effective as an antihypertensive agent.
