PROCESS FOR PREPARING 8-PHENYL-PURINES

摘要

The phenylpurine [1 (R1 = H, halogen, R2S, R2SO, R2SO2, alkoxy optionally substituted by R2S, R2SO, or R2SO2; R2=R2O; R2 = alkyl) and their salts were prepared for use in heart in sufficiencies or cardiogenic shock. Thus 4,5-diaminopyrimidine-HCl, 2,4-MeO(C6H3COCl, and POCl3 were refluxed 3 hrs. to give 44% I (R1 = 4-Mes, R2 = 2-MeO) .
