These compounds are useful as anti-asthmatic, anti-allergic and anti-inflammatory agents and are made into pharmaceutical compositions. In the formula, R1 is a radical of formula COOR3, where R3 is hydrogen or an alkyl or cycloalkyl group containing not more than six carbon atoms; CH2OH; CHO; CH2NHSO2R4, where R4 is OH; C1-6 alkyl, C1-6 alkoxy phenyl, phenyl substituted by C1-3 alkyl or C1-3 alkoxy, halogen, hydroxy, haloalkyl, COOH, CN, formyl, C1-6 acyl or C1-4 peRfluoroalkyl; CN; or CON(R5)2, where each R5, independently of the other, is H, OH or C1-4 alkyl; a tetrazolyl radical, a monocyclic or bicyclic heterocyclic ring containing an acidic @hydroxyl@ group; or a radical of formula where each s, independently of the other, is 0, 1, 2 or 3; R2 is (A) a monocyclic or bicyclic heterocyclic radical containing from 3 to 12 nuclear carbon atoms and 1 or 2 nuclear heteroatoms, one being N, and the other (if any) being N or S, each ring in the heterocyclic radical having 5 or 6 atoms, or (B) a radical X-R8 where X is O, S or NH and R8 contains up to 21 carbon atoms and is (1) a hydrocarbon radical or (2) an acyl radical derived from an organic acyclic or monocyclic carboxylic acid containing not more than 1 heteroatom that is N, O or S in the ring; and each R10, independently of the other is H or C1-4 alkyl; R6 is H or C1-4 alkyl; R2 is a halogen atom; and R9 is a hydrogen atom or hydroxyl group.
