Chemical Compounds

A compound of formula (I)

• or a tautomer thereof, or a pharmaceutically acceptable salt or solvate of said compound or said tautomer, wherein:
• one of X and Y is C and the other is N;
• R1 is selected from
• H, F, Cl and CF3;
• one of R2 and R3 is selected from
• (C3-C6)alkyl,
• (C3-C6)cycloalkyl,
• adamantyl, and
• phenyl substituted with —CN, and optionally further substituted with one or two groups independently selected from —F, —Cl, —CF3 and —CN;
• and the other one of R2 and R3 is selected from
• H and F;
• R4 is selected from
• H, F, Cl and CF3
• R5 is selected from
• (C1-C6)alkyl,
• (C1-C6)alkyl substituted with a group selected from
• —CONH2,
• —CONH—(C1-C3)alkyl,
• —CON((C1-C3)alkyl)2 wherein the (C1-C3)alkyl groups may be the same or different,
• —OH,
• —O(C1-C3)alkyl, and
• —OCONH2,
• (C3-C6)cycloalkyl, and
• phenyl,
• R6 is selected from
• H and (C1-C3)alkyl,
• or R5 and R6 together with the carbon atom to which they are attached may form a 3- to 6-membered cycloalkyl moiety which may optionally be benzo-fused;
• R7 is H or methyl,
• or, when R5 and R6 do not form a cycloalkyl or benzo-fused cycloalkyl moiety, R5 and R7 together with the carbon and nitrogen atoms to which they are attached may form 4- to 6-membered monocyclic or 6- to 8-membered bicyclic saturated nitrogen heterocycle which may optionally be substituted with 1 or 2 groups selected from —(C1-C3)alkyl, —OH, and —F.
