1. A compound of formula:
- ##STR5## in which either;
(1) - R1 represents polyfluoroalkoxy, tert-butyl, or trimethylsilyl, and R2 and R3 represent hydrogen, with the proviso that, when R1 represents trifluoromethoxy, R2 and R3 are not both hydrogen;
(2) - or R1 represents polyfluoroalkoxy, R2 represents hydrogen, and R3 represents amino or phenylalkyl;
(3) - or R1 represents polyfluoroalkoxy, R2 represents amino and R3 represents hydrogen, provided that said alkyl and alkoxy radicals or portions contain 1to 4 carbon atoms each in a straight or branched chain, or a pharmaceutically acceptable salt of a said compound with an inorganic or organic acid.
