A series of novel methylene-bis-pyrimidinyl-spiro-4-thiazolidinones 6a-h have been synthesized by cyclocondensation of thioglycolic acid with methylene-bis-(N-cyclohexylidene-N-pyrimidine) 5a-h, which in turn have been prepared by the reaction of cyclohexanone with methylene-bis-2-aminopyrimidines 4a-h, which are prepared by the reaction of guanidine hydrochloride with methylene-bis-chalcones 3a-h
