Reaktionsschritte

Compound No. 13: A suspension of 3,5-diacetylaniline (1.95 g) in water (10 mL) was treated with 2-chloro-4,6-diamino-1,3,5-triazine (1.455 g) and concentrated HCl (0.1 mL) and heated at reflux for 20 min. After cooling the hydrochloride of Compound No. 13 separated as a white powder. This was filtered out, dissolved in 60 mL of boiling aqueous 75% methanol and treated with triethylamine (1.5 mL). On cooling, off-white flakes separated. Filtration and drying gave 1.79 g of 2-(3,5-diacetylphenyl)amino-4,6-diamino-1,3,5-triazine, mp 271°-2° C.
