Abstract
A facile synthesis of novel 2-amino-6-arylmethyl-7-carboxamido-7,8-dihydropyrimido[5,4-f][1,4]thiazepin-5-ones is described. The synthesis was developed on solid phase and was applied to provide a series of analogs in good yield. The key reactions are acylation of a cysteine derivative with 2,4-dichloropyrimidine-5-carbonyl chloride followed by cyclization to generate a 6-arylmethyl-7-carboxamido-2-chloro-7,8-dihydropyrimido[5,4-f][1,4]thiazepin-5-one, which is further derivatized with an amine to give the desired 2-amino-6-arylmethyl-7-carboxamido-7,8-dihydropyrimido[5,4-f][1,4]thiazepin-5-one.
