Abstract:
A process for preparing a compound of Formula (I): ##STR18##where Q completes an optionally substituted 5- or 6member saturated carbocyclic ring and R is optionally substituted phenyl or optionally substituted C.sub.3 -C.sub.6 cycloalkyl which process comprise the rearrangement of a compound of Formula (II) ##STR19##where Q and R are as defined in relation to Formula (I) in a polar aprotic, dipolar aprotic or aromatic hydrocarbon solvent in the presence of a moderate base and an azole compound of Formula (III) ##STR20##in which A is N or CR.sup.22 ; B is N or CR.sup.23 and R.sup.21, R.sup.22 and R.sup.23 are independently H, alkyl, or aryl or when B is CR.sup.23, R.sup.21 and R.sup.23 together with the carbon atoms to which they arc attached form a 6-membered carbocyclic ring and salts thereof.
