摘要：
The title compound N-(5,7-dimethoxy-2H-[1,2,4]thiadiazolo[2,3-a]pyrimidin-2- ylidene)-2-(2,4-dichlorophenoxy)propanamide 3 has been synthesized through using bromine as cyclic reagent in 66% isolated yield. Suitable single crystals for X-ray diffraction were obtained by recrystallization from the mixture solvents at room temperature. Crystallographic data of 3: C32H28Cl4N8O9S2, Mr = 874.56, monoclinic, space group P21/c, a = 18.612(8), b = 14.084(6), c = 14.757(6), α = 90.00, β = 95.505(7), γ = 90.00o, Z = 4, V = 3850(3)3, Dc = 1.509 g/cm3, F(000) = 1792, R = 0.0704, wR = 0.1454 and μ = 0.479 mm-1. The title compound 3 was found to be effective in herbicidal activity
