The solid supported synthesis of functionalized 1,2,4-triazin-6-ones from resin bound amino acids and acid chlorides is described. A thioamide intermediate is generated with Lawesson's reagent, and the final products are cyclized and cleaved from resin with hydrazine. The products are obtained in good yield and purity.
