Page/Page column 122; 123, (2013/04/13)
A heterocyclic compound useful as an antiallergic agent is provided. A compound represented by the following formula (1) or a salt thereof: wherein the ring A is a homocyclic or heterocyclic ring; the ring B is a heterocyclic ring which contains G and nitrogen atom N as constituent atoms thereof, wherein G is CH or N; R1 is a carbonyl group or an alkylene group; R2a and R2b are an alkyl group, a cycloalkyl group, an aryl group, or a heterocyclic group; X is an oxygen atom or a sulfur atom; Z is a hydroxyl group, an alkoxy group, a cycloalkyloxy group, an aryloxy group, an aralkyloxy group, an amino group, or an N-substituted amino group; and n is 0 or 1; with the proviso that when the ring A is a benzene ring or when the ring B is a piperazine ring, R1 is an alkylene group which may have a substituent.

A process for advantageously preparing a piperazinesulfonamide derivative represented by the general formula (III): wherein R1 is hydrogen atom, a straight or branched chain alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, a halogen atom, hydroxyl group, trifluoromethyl group, nitro group or amino group; R2 is a phenyl group which may have as substituents on its phenyl ring 1 to 3 groups selected from the group consisting of an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, a halogen atom, hydroxyl group, trifluoromethyl group, nitro group and amino group, 2-pyridyl group, 3-pyridyl group or 4-pyridyl group; each of R3 and R4 is independently hydrogen atom, a straight or branched chain alkyl group having 1 to 6 carbon atoms, a hydroxyalkyl group having 1 to 4 carbon atoms, a cycloalkyl group having 3 to 8 carbon atoms, or a phenyl group which may be substituted; and Y is an alkylene group having 1 to 12 carbon atoms, and a salt thereof.
