A photoresist composition containing a polymer having a structural unit including an acid-labile group, and a compound represented by the formula (1). In the formula (1), R
1
represents a hydrogen atom or a monovalent acid-labile group. R
2
represents an alicyclic hydrocarbon group having 3 to 20 carbon atoms and a valency of (m+1). m is an integer of 2 to 5. R
3
and R
4
each independently represent a hydrogen atom, a fluorine atom, a monovalent hydrocarbon group having 1 to 20 carbon atoms or a monovalent fluorinated hydrocarbon group having 1 to 20 carbon atoms. n is an integer of 0 to 5. At least two of a plurality of R
1
s optionally taken together represent a ring structure, together with a plurality of oxygen atoms bonding to R
1
and the carbon atom(s) constituting R
2
and bonding to these oxygen atoms. M
+
represents a monovalent radiation-degradable onium cation.

O and p=0-1; and G denotes low-molecular-weight organic or mineral acid, sodium, potassium or ammonium cations, or water. Said derivatives have antiaggregant, anticoagulant and vasodilatory properties. The invention further relates to a method for producing said derivatives by reacting N-substituted piperazines either with carboxamide amidating agents or salts thereof, or with haloalkyl sulfonic acids or salts thereof in organic solvents or in water in the presence of bases. The compounds may be used for the prophylaxis and treatment of disorders of the hemostatic system.
