Abstract: A compound of formula (I), a pharmaceutically acceptable salt or solvate thereof, wherein R' represents C,-C6 alkyl, -(CH2)c-[C3-C8 cycloalkyl]-, - (CH2)C -W or -(CH2)C-Z-(CH2)dW; W represents C1-C6 alkyl, C1-C6 alkyloxy, - C02[C1-C6 alkyl], -CONR4R5, an optionally substituted phenyl group, NR4R5, het2 or het3; Z represents O or S(O)g; g represents 0, 1 or 2; R2 represents a phenyl group, optionally fused to a 5- or 6- membered aryl or heterocyclic group which may contain one or more heteroatoms selected from N, O or S; the phenyl group and the optionally fused group being optionally substituted; Ri ng A represents a 4-, 5- or 6- membered saturated heterocyclic group containing at least one N; Ring B represents a phenyl group or het1, each group being optionally substituted; R7 independently represents H1 C1-C6alkyl, OR3, - (CH2)e-R3 or -(CH2)f-O-(CH2)e-R3; at each occurrence R3 independently represents H1 C1-C6 alkyl optionally substituted by Y, -(CH2)g [C3-C8 cycloalkyl], phenyl, benzyl, pyridyl or pyrimidyl; at each occurrence R4 and R5independently represent H1 Cl-C6 alkyl (optionally substituted with Cl-C6 alkyloxy), (CH2)gC02-[C1-C6 alkyl], -S02Me, -(CH2)g [C3-C8 cycloalkyl], S02M e, phenyl, benzyl, pyridyl or pyrimidyl; or R4 and R5 together with the N atom to which they are attached represent a heterocyclic group of from 3 to 8 atoms; Y independently represents a phenyl group, NR4R5 or het4, the phenyl group bei ng optionally substituted; het1 represents a 4-, 5- or 6- membered saturated, o r unsaturated, heterocyclic group containing at least one N (but which may als o contain one or more O or S atoms); het2 and het4 represent an optionally substituted 4-, 5-, 6- or 7- membered saturated, or unsaturated, heterocycli c group containing at least one N (but which may 5 also contain one or more O or S atoms); het3 represents an optionally substituted 4-, 5-, 6- or 7- membere d saturated, or unsaturated, heterocyclic group containing at least one O (but which may also contain one or mare N or S atoms); at each occurrence R6 independently represents H1 C1-C6 alkyl optionally substituted by Y, =(CH2)g [C3-C8 cycloalkyl], phenyl, benzyl, pyridyl or pyrimidyl; a and b independently represent 0 or 1; c,, d, a end g independently represent 0, 1, 2, 3 or 4; . f índeperldently represents 1, 2, 3 or 4; provided that: (i) a + b cannot equal 0; and províded,that,when R1 represents -(CH2)c-Z-(CH2)d-W an d W represents.NR4R5 or any N linked heterocyclic, group then d must not be, 0 or 1; and (iii), provided that when R2 represents a phenyl group substituted by a group of, formula -(CH2)eOR3, -(CH2)e-OCOR3 or -(CH2)e,OCOR3 ;or het1,and/or het2 are substituted by a group of formula -(CH2)eOR3, (CH2),- CO2R3 or -(CH2)eOCOR3; or when R7 represents -OR3 or -(CH2)f-0-(CH2)e-R3 and e is 0; or when W represents a phenyl group substituted with -OR3 or - C02R3 a nd R3 represents an alkyl group substituted with Y, and Y represents NR4R5 or a n N-Finked het3; then, R3, must,represent,C2-C6 alkyl substituted with. Y. are useful in the treatment of dysmenorrhoea.
