Synthesis and Crystal Structure of 2-(4-Methoxy- 6-methylthio-2-pyrimidinyl)aminocarbonyl-aminosulfonyl Benzoic Acid Methyl Ester

摘要

The title compound 2-[(4-methoxy-6-methylthio-2-pyrimidinyl)aminocarbonyl-aminosulfonyl]benzoic acid methyl ester (C15H16N4O6S2,Mr = 412.44) was obtained by the reaction of (4-methoxy-6-methylthio-2-pyrimidinyl)amine with 2-methoxylcarbonylbenzene-sulfonylisocya-nate.The crystal is of monoclinic,space group P21/c with a =11.169(3),b = 9.508(3),c = 17.690(5)(A),β = 91.593(5)o,Z = 4,V = 1877.9(10)(A)3,Dc = 1.459 g/cm3,F(000) = 856,μ(MoKα) = 0.324 mm-1,R = 0.0690 and Wr = 0.1368 for 3301 observed reflections (I > 2((I)).The N(1)-H…N(3) and N(2)-H…O(4) hydrogen bonds can be observed.In the molecule the phenyl plane(I),pyrimi-din-2-yl-urea bridge plane(Ⅱ) and ester plane(Ⅲ) form three conjugated systems.
