실험 절차

To a solution of 6a (10 mg, 0.0155 mmol) in water (100 μL) was added dropwise 1M thiophosgene in CHCl3 (18.6 μL, 0.0186 mmol). The resulting mixture was stirred at room temperature for 3 h. The aqueous layer was concentrated in vacuo to provide pure 7a (10 mg, 99%) as a light yellowish solid. 1H NMR (MeOD, 300 MHz) δ 2.50-4.55 (m, 24H), 7.10-70 (m, 4H).
