Vollmann found that the reaction between l-imino-3-amino isoin dolenine (124) and 2-amino-4-methylthiazole is catalyzed by ammonium chloride and involves the exocyclic nitrogen (285). This reaction (Scheme 82) was later used to prepare dyes (286).  [c.56]

Heating the 5-isocyano-l,3,4-thiadiazolo[3,2- ]pyrimidin-5-one 115 with 10% hydrochloric acid gave a mixture of the 5-imino-l,3,4-thiadiazolo[3,2- ]pyrimidin-7-one 116 (10%) and the l,2,4-triazolo[l,5-c]pyrimidine-5,7-dione 117 (35%) (91JHC489). Formation of 117 probably occurred through thiadiazole ring rupture of 116 and recyclizatioii with its imino function together with desulfurization (Scheme 43).  [c.367]
