9,9-Dialkyloctahydropyrimido[3,4-a]-s-triazines were synthesized by iminodimethylation reaction between a 5,5-dialkyl-6-aminopyrimidine-2,4(3H,5H)-dione, a substituted aniline and two moles of formaldehyde. The synthesis of 5,5-dialkyl-6-aminopyrimidinedione consisted of the condensation of urea with ethyl 2,2-dialkylcyanoacetates. 18 Octahydropyrimido[3,4-a]-s-triazines were synthesized and compounds resulting from a supplementary aminomethylation were also obtained. Most of these compounds were tested for antifungal activity in vitro. Only 9,9-dibutyl-6,8-dioxo-3(2-chlorophenyl)2,3,4,5,6,7,8,9-octahydropyrimido[3,4-a]s-triazine showed some activity against Microsporum canis.
