| | 7-(DIETHYLAMINO)-5-METHYL-S-TRIAZOLO[1,5-A]PYRIMIDINE Usage And Synthesis |
| Chemical Properties | White or almost white, crystalline powder | | Originator | Rocornal,Mochida,Japan,1978 | | Uses | Vasodilator;PDGF antagonist | | Definition | ChEBI: Trapidil is a member of triazolopyrimidines. | | Manufacturing Process | 8.4 g of 5-methyl-7-chloro-s-triazolo-(1,5-a)-pyrimidine were suspended in 30
cc of water and 7.3 g of diethylamine added. After 2 hours heating with
stirring, the mixture was concentrated under vacuum. The residue was
recrystallized from n-heptane. This process yielded 8.1 g of the 5-methyl-7-
diethylamino-s-triazolo-(1,5-a)-pyrimidine having a melting point of 103°C to
104°C. The hydrochloride produced in the usual manner had a melting point
of 212°C. | | Therapeutic Function | Coronary vasodilator | | Safety Profile | Poison by ingestion,
intraperitoneal, subcutaneous, and
intravenous routes. An experimental
teratogen. Other experimental reproductive
effects. A coronary vasodilator. When
heated to decomposition it emits toxic
fumes of NOx. See also MINES. |
