To 200 mg (0.62 mmol) of 3-(3-trifluoromethylbenzamido)benzhydrazide in 2.5 mL of tetrahydrofuran was added 157 mg (121 μL, 0.93 mmol) of 2-chlorophenyl isothiocyanate. The reaction was stirred at room temperature overnight. After concentration by rotoevaporation, the residue was purified by preparative HPLC to give 219 mg (0.44 mmol, 72% yield) of 4-(2-chlorophenyl)-1-[3-(3-trifluoromethylbenzamido)-benzoyl]thiosemicarbazide. 1H NMR (CDCl3): δ7.28 (d of t, 1H), 7.36 (d of t, 1H), 7.49 (d of d, 1H), 7.55 (t, 1H), 7.69 (d, 2H), 7.74 (t, 1H), 7.94 (d of t, 2H), 8.21 (d, 1H), 8.27 (s, 1H), 8.36 (s, 1H), and 9.09 ppm (s, 1H). MS m/z: 493.0 (M+H).
