Abstract
derivs. of formula (I): (where R is H or 1-10C alkyl) are prepd. by hydrolysis of a cpd. of formula (II): (where R1 is H, 1-4C alkyl, phenyl or 7-15C aralkyl; Y is trialkylamino or an opt. substd. heterocyclic ring with a tert. N atom via which it is bonded to the CR1 gp.). Cpds. (I) are antibacterial agents, e.g. (I; R=H) is used in the treatment of urinary tract infections. The process gives high yields (e.g. 76-93%) of cpds. (I) in pure form.
