description	It has been found that the novel compounds of the formula wherein R is hydrogen or lower alkyl, R is hydrogen or halogen, R is hydrogen or lower alkyl, R is hydrogen or lower alkyl, R is hydrogen, lower alkyl or aralkyl, X is alkylene and n is an integer from 1 to 6, the enantiomers thereof and, when R is hydrogen, the salts thereof with pharmaceutically acceptable bases have antiallergic properties and can accordingly be used as medicaments for the treatment or prevention of allergic conditions. The compounds of formula I can be manufactured by reacting a compound of the formula with a compound of the formula and optionally hydrolyzing the compound thus obtained.
