    Abstract: A process for isolating a compound of formula (I) or a salt thereof, where X and R1 are as defined in the specification, from a mixture containing it, and the corresponding diacid and dihydroxy derivative, said process comprising (i) adding to an organic solution containing said compounds, water and a one or more salts, all of which are bases selected from a carbonate or hydrogen carbonate base, (ii) separating the aqueous phase containing the compound of formula (II) from the organic phase containing the compounds of formula (I) and (III); then (iii) recovering the compound of formula (I) from remaining organic phase. The process provides for efficient isolation of the target compound, even on a large scale.

    Abstract: A process for preparing a compound of formula (I) where R4 and R5 are as defined in the specification; and R6 is hydrogen or a protecting group, which process comprises cyclisation of a compound of formula (II) where R4, R5 and R6 are as defined in relation to formula (I), and R7 is nitrogen-protecting group, and removing the group R7—, and thereafter if desired or necessary, removing any protecting group R6 to obtain the corresponding carboxylic acid. Novel intermediates and the use of the products in the preparation of pharmaceutical compounds is also described and claimed.
