摘要

4-Amino-2-imidazolidinonyl-pyrimidin-5-carboxamide derivatives of formula (I), and their salts, are new. R1 = H or 1-8C alkyl; Ar = phenyl substituted by R2 and R3; R2 = F, Cl, Br, H, 1-8C alkoxy or 1-8C alkylthio; R3 = 1-8C alkoxy or 1-8C alkylthio; or R2+R3 = 1-5C alkylene dioxy; all alkyl groups are optionally substituted by 1 or more F.
