The use is disclosed of compounds of the formula (I):-
where R' is methoxy, methylthio, trifluoromethyl, chloro, fluoro or bromo; R2 is hydrogen or with R1 is methylenedioxy; R3 is hydrogen or methyl; n is 0, 1 or 2; andX is -(CH2)m- where m is 0 to 4, 1,2-propanediyl, 1,3-propan-2 -oldiyl or 1,3-propan -2-onediyl and their pharmaceutically acceptable salts, provided that m is not 0 when R1 is chloro, as anti-arthritic agents. Also disclosed are pharmaceutical compositions comprising a compound of formula (I) as defined above or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier.
Some compounds of formula (I) are novel, such compounds have formula (I) where R' is methoxy, methylthio, trifluro-methyl, chloro, fluoro or brom; R2 is hydrogen or with R1 is methylenedioxy; R3 is hydrogen or methyl; n is 0, 1 or2; and X is -(CH2)m- where m is 0 to 4, 1,2-propanediyl, 1,3-propan-2 -oldiyl or 1,3-propan-2-onediyl, and pharmaceutically acceptable salts, provided that when R1 is chlorom is not 0 and when R1 is methoxy and n is 0 m is not 2. A process is disclosed for the preparation of these novel compounds.
