HCID 146976571-Methyl-5-phenyl-1H-1,5-benzodiazepine-2,4(3H,5H)-dione

Procedure

Starting from 1-phenyl 1,2,4,5-tetrahydro 2,4-dioxo 3H-1,5-benzodiazepine, obtained in the example VIII, by acting methyl chloride in the presence of sodium ethanolate, there is obtained 1-phenyl 5-methyl 1,2,4,5-tetrahydro 2,4-dioxo 3H-1,5-benzodiazepine, melting at 144°-146° C. after recrystallisation in isopropanol.
