The novel title compound (Z)-N-(4-bromo-5-ethoxy-3,5-dimethylfuran-2(5H)-ylidene)-4-methylbenzenesulfonamide 1 (C15H18BrNO4S) has been unexpectedly synthesized by the aminohalogenation reaction of ethyl 2-methylpenta-2,3-dienoate with TsNBr2, and characterized by mp, IR, 1H NMR, EIMS, ESIHRMS and single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P21/c with a = 11.714(5), b = 14.106(5), c = 10.402(4)(A), β = 97.298(8)°, V=1704.9(12)(A)3, Mr = 388.27, Z = 4, Dc = 1.513 g/cm3,μ(MoKα) = 2.549 mm-1, F(000) = 792, the final R = 0.033 and wR = 0.062 for 3098 observed reflections (Ⅰ＞ 2σ(Ⅰ)).
