According to the invention there is provided compounds of formula (1): Wherein: X represents a bond, oxygen, NR3 or a group (CH2)n wherein n represents 1 of 2; Y represents =(CH2)qNHC(O), -(CH2)qO(CH2)p, -(CH2)qS(CH2)p, -(CH2)qC(O)(CH2)p, (CH2)qSO2(CH2)p, -(CH2)qCH=CH(CH2)p, -(CH2)pCH(OH)(CH2)p, -C(O), -(CH2)3,-(CH2)qNH, - (CH2)qNHCONK or -(CH2)qCONH; wherein q represents 1 or 2 and p represents 0 or 1; Ar1 represents a phenyl, naphthyl or 5 or 6 membered heteroaryl group containing up to 3 heteroatorns selected from N, O, and S, or a bicyclic heteroaryl group containing up to 3 heteroatoms selected from N, O and S any ofwhich can be optionally substituted; Ar2 represents an optionally substituted phenyl or a 5- or 6-membered'heteroaryl group containing up to 3 heteroatoms selected from N, O and S; Ar3 represents an optionally substituted R5.is-O (CH2)mNR1R2 Or (CH2)mNR1 R2 each of R1 and R2 independently represents a hydrogen atom or an optionally substituted (C1-6)alkyl group or R1 and R2 together with the nitrogen to which they are attached form part of a (C3-6)azacycloalkane or (C3-6)(2-oxo)azacycloalkane ring, or R1 with at least one CH2 of . the (CH2) m portion of the group form a (C3-6) azacycloalkane and R2 represents hydrogen, an optionally substituted (C1-6)alkyl group, piperidine, pyrrolidine, morpholine or with the nitrogen to which they are attached forms a second (C3-6)azacycloalkane fused to the first (C3-6)azacycloalkane; R3 represents hydrogen or optionally substituted (C1-6) alkyl; m represents an integer from '2 to 6; and Ar3 is attached to Ar2 ortho to the amide carbonyl group; The compounds of formula (I) and their pharmaceutically acceptable derivatives are useful for the treatment of diseases or disorders where an antagonist of a human orexin receptor is required
