ring. The products containing ester or acid groups at the C-4 position of the 1,3-thiazoline ring were used in amide synthesis to give a new sublibrary within Chemset C. Deprotection of the phthalimidyl moiety of 24 followed by the reaction with benzoyl chloride gave the corresponding sublibrary in Chemset C. Another sublibrary which includes secondary amino derivatives was obtained by reduction of
