There are described compounds of formula 1,
in which R,, R2, R3, Rs and R6 are as defined in the specification and R4 is a phenyl group carrying 3 or 4 substituents or is an unsaturated 5 membered heterocyclic group containing a single hetero-atom selected from oxygen, sulphur or nitrogen, R4 being substituted by CF3, XR22, nitro, halogen, CN, alkyl C1 to 6, formyl dioxalanyl, -N(R23)COR24 -CONR25R26, or amino which is optionally substituted by phenylsulphonyl or by trifluoroacetyl, and R4 carries a substituent on the atom adjacent to the atom through which R4 is connected to the remainder of the molecule,
R22 is phenyl or alkyl C1 to 6 optionally substituted by halogen,
X is 0 or S(O)n,
n is 0, 1 or 2, and
R23, R24, R25 and R26, which may be the same or different, are each hydrogen or alkyl C1 to 6.
There are also described methods for making the compounds, and their formulation and use as pharmaceuticals, eg for the treatment of cardiovascular conditions.
There are further described compounds R4CHO which are useful in making compounds of formula I.
