Versuchsvorschrift

Benzoylisothiocyanate (0.12 mL, 0.91 mmol) was added dropwise to a solution of benzothiazole-2,6-diamine (Example 1, 150 mg, 0.91 mmol) in 10 mL of THF at room temperature. The mixture was stirred at room temperature for 7 hours and then concentrated. The residue was washed with a 1:1 mixture of Et2O and hexanes. Yield: 97.3%, 1H-NMR (DMSO-d6): δ 12.65 (s, 1H); 11.55 (s, 1H); 8.00 (m, 3H); 7.60 (m, 5H); 7.38 (m, 2H).
