摘要

Reaction of thiazolidin-2-cyanamide and substituted benzyl bromide compounds in acetonitrile at room temperature afforded the 3-(2 '-substituted benzyl)thiazolidin-2-cyanamide derivatives1-13in good yields. Compounds1-13were characterized by proton nuclear magnetic resonance (H-1 NMR) and infrared spectroscopies, of which the structures of the isomerico-,m-, andp-fluoro derivatives4-6were established by single crystal X-ray crystallography. Compound4crystallizes in the monoclinic space group P2(1)/n, witha = 9.177(19), b = 8.551(18), c = 14.090(3) angstrom, beta= 98.243(3)degrees, and Z = 4. The unit cell of 5 has a monoclinic P2(1)/csymmetry with the cell parametersa = 9.289(2),b = 14.057(4),c = 8.574(2) angstrom, beta= 100.350(3)degrees, and Z = 4. The unit cell of 6 also has a monoclinicP2(1)/csymmetry with the cell parametersa = 9.333(4), b = 14.034(5), c = 8.508(3) angstrom, beta= 99.15(5)degrees, and Z = 4.
