General description

p-Tolyl isothiocyanate reacts with 6-hydroxy-2,4,5-triaminopyrimidine or with 4,5,6-triaminopyrimidine in DMF and triethylamine to yield 2,4-diamino-5-(p-tolylthioureido)aminopyrimidin-6-one and 4,6-diamino-5-(tolylthioureido)aminopyrimidine, respectively.

Application

p-Tolyl isothiocyanate has been used:
  • in the preparation of 6-[1-amino-3-(p-tolyl)-thiourea]-2-ethylbenzo[de]isoquinoline-1,3-dione
  • as capping agent to cap the N-terminal ends of polypeptides

Methods for direct synthesis of N-(purin-8-yl)arylamines were investigated. N-(Purin-8-yl)arylamines are adducts from reaction of electrophilic metabolites of arylamines with DNA and have not been readily available by direct synthesis. Ability to generate significant quantities of this class of DNA adduct
