The invention provides novel compounds of formula (I). STR1 and pharmaceutically acceptable salts thereof wherein R1, R2, R3 and R4 which may be the same or different, represent hydrogen, halogen, lower alkyl, and lower alkoxy, or any adjacent two of R1 to R4 taken together represent an alkylene group containing from 3 to 5 carbon atoms or a 1,4-buta-1,3-dienylene group. The compounds are useful as anti-allergic agents.
