Abstract
Imidazo 2,1-a isoindoles useful as anorexigenics and CNS stimulants. Processes for the preparation of title cpds. of formula (I) (where R and R1 are H, F or Cl) are claimed. Also claimed are cpds. of formula (II) (where R3 is H or phenyl) and their salts with mineral and organic acids, which have anorexigenic activity. (II; R3 = H) are intermediates for (I). Other intermediates in the prepn. of (I) are also claimed.
