The compounds of formula (I) and their pharmacologically acceptable acid addition salts are useful in medicine.
In formula (I)
Y is a group selected from alkylthio, alkenylthio, arylthio, alkylsulphinyl, alkenylsulphinyl, arylsulphinyl, alkylsulphonyl, alkenylsulphonyl, arylsulphonyl, alkoxy, alkenyloxy, or aryloxy, in which group any hydrogen atom is optionally replaced by a halogen atom;
each X is the same or different and is independently selected from alkylthio, alkenylthio, arylthio, alkylsulphinyl, arylsulphinyl, alkenylsulphinyl, alkylsulphonyl, alkenylsulphonyl, arylsulphonyl, alkoxy, alkenyloxy, aryloxy, alkyl, alkenyl, aryl, trihaloalkyl, or halogen;
n is 0 to 4;
R1 is hydrogen, alkyl, alkenyl, alkynyl, aralkyl or aryl;
R2 is hydrogen, alkyl, acyl of 1-4 carbon atoms, aroyl of 6-10 carbon atoms or alkoxycarbonyl; or
R1 and R2 together represent
where X is a suitable substituent and m is 0-5; and
R3and R4 are the same or different and each represents hydrogen or alkyl
provided that when R1 is other than hydrogen, R2 is not acyl or aroyl.
