Novel phenylindene derivatives of the present invention are represented by the following formula:
wherein the dotted lines indicate optional bonds;
R1 is hydrogen, halogen, lower alkyl, lower alkoxy, hydroxymethyl, lower alkoxymethyl, cyano, trifluoromethyl, lower alkylthio or lower alkylsulfonyl;
R2 is halogen, lower alkyl or trlfluoromethyl; and
R3 is hydrogen, alkyl or alkenyl (straight or branched chain with C1-C6 inclusive) optionally substituted with one or two hydroxy groups, any hydroxy group present being optionally esterified with an aliphatic carboxylic acid having from two to twenty-four carbon atoms inclusive, or R3 is
wherein Z ist NR4, 0 or S, where R4 is H or lower alkyl, and W is 0 or S, as well as pharmaceutically acceptable acid addition salts of the compounds of Formula I.
The phenylindene derivatives of Formula I have Interesting pharmacodynamic properties indicating strong antipsychotic activity.
Methods for the preparation of said derivatives are also described, as well as novel intermediates, wich are useful in the methods.
