Abstract:Riluzole was firstly transformed into (6-trifluoromethoxy-benzothiazol-2-yl)-hydrazine, then was chloridized by SOCl2 to obtain 2-chloro-6-trifluoromethoxybenzothiazole(3). The novel compound, 2-(N-cyclohexylamine)-6-trifluoromethoxybenzothiazole(4), was synthesized by substitution reaction of 3 with cyclohexylamine. The structure was characterized by 1H NMR, IR, elemental analysis and X-ray single crystal diffraction. 4(CCDC: 1 440 686) belongs to triclinic system, space group P-1 with a=10.617(3) , b=13.607(4) , c=16.619(5) , V=2 201.8 3, Dc=1.422 g·cm-3, Z=6, R1=0.082 0, wR2=0.235 1.
