Regioselective synthesis of 2-oxo-2,8-dihydro-[1,2,4]oxadiazolo[2,3-a]pyrimidine-7-carbamates: a new class of antihypertensive peripheral vasodilators was written by Muller, Jean Claude; Ramuz, Henri. And the article was included in Helvetica Chimica Acta in 1982.Formula: C4H5ClN4O The following contents are mentioned in the article:
Oxadiazolopyrimidinecarbamates I (R = Me, Et, Bu, CH2CHMe2, CH2Ph, CH2CH2OMe) were prepared by oxidizing 6-chloro-2,4-pyrimidinediamine to give 3-oxide and reaction with tetrahydropyridine to give II (R1 = H). Treatment of II (R1 = H) with RO2CCl gave II (R1 = CO2R) which cyclized to I on heating. I, especially I (R = Me), have antihypertensive activity. This study involved multiple reactions and reactants, such as 2,6-Diamino-4-chloropyrimidine-1-oxide (cas: 35139-67-4Formula: C4H5ClN4O).
2,6-Diamino-4-chloropyrimidine-1-oxide (cas: 35139-67-4) belongs to pyrimidine derivatives. Pyrimidine also found in many synthetic compounds such as barbiturates and the HIV drug, zidovudine. Pyrimidine derivatives also play an important role in drug development, either in concert with other compounds or on their own.Formula: C4H5ClN4O
