1-Chloro-2-isothiocyanatobenzene → HCID 58725959, compound

Participants

Reaction Steps

To 200 mg (0.69 mmol) of 3-(3-chlorobenzamido)benzhydrazide in 2.5 mL of tetrahydrofuran was added 175 mg (135 μL, 1.04 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 243 mg (0.53 mmol, 77% yield) of 1-[3-(3-chlorobenzamido)benzoyl]-4-(2-chlorophenyl)thiosemicarbazide. 1H NMR (CDCl3): δ7.28 (d of t, 1H), 7.35 (d of t, 1H), 7.99 (t, 1H), 8.34 (br s, 1H), and 8.98 ppm (br s, 1H). MS m/z: 459.0 (M+H).
