Abstract

The title compound, ethyl 5-amino-1-[(5?-methyl-1?-t-butyl-4?-pyrazolyl)carbonyl] -3-methylthio-1H-pyrazole-4-carboxylate 5, has been synthesized by the treatment of 4 with ethyl 2-cyano-3,3-dimethylthioacrylate, and its crystal structure was determined by X-ray diffraction method. The crystal belongs to monoclinic, space group P21/c with a = 12.194(4), b = 12.909(4), c = 11.607(4) ?, β = 90.183(5)°, V = 1827.2(10) ?3, Mr = 365.45, Z = 4, Dc = 1.328 g/cm3, μ = 0.203 mm-1, F(000) = 776, R = 0.0586 and wR = 0.1558. Preliminary bioassays indicated that the title compound shows fungicidal and plant growth regulation activities.
