There are disclosed compounds having the formula
wherein
X is CR or N when n=1; or
X is 0, S, NR or CR when n = 0;
R is hydrogen or lower alkyl;
Y is -CH2-, -S-, -0- or -N-; and R
A is
Z is CH or N;
R1 is halo or trifluoromethyl;
R2 is hydrogen or halo:
R3 is hydrogen or halo;
with the proviso that when A is naphthyl, Y is -0- and n=O, X is other than S. The compounds are useful in the treatment of inflammatory conditions and in the treatment of leukotriene- mediated naso-bronchial obstructive passageway conditions.
