The invention provides a compound of formula (I) or a salt thereof: formula (I) wherein W is Ar, -CR4R5Ar or a group (y) or (y1), wherein Ar is (x) or (z): formulae (x), (z), (y), (y1) R1 is C1-4alkyl, C1-3fluoroalkyl or CH2CH2OH. R2 is C2-6alkyl, C3-6cycloalkyl or -(CH2)n4-C3-6cycloalkyl; and R3 is optionally substituted C3-8cycloalkyl, optionally substituted mono unsaturated C5-7cycloalkenyl, an optionally substituted heterocyclic group (aa), (bb) or (cc) (in which Y is O, S, SO2, or NR10), or a bicyclic group (ee): formulae (aa), (bb), (cc), (ee). The invention also relates to the use of the compounds in therapy as inhibitors of phosphodiesterase type IV (PDE4), and/or for the treatment and/or prophylaxis of inflammatory and/or allergic diseases such as chronic obstructive pulmonary disease (COPD), asthma, rheumatoid arthritis or allergic rhinitis.
