실험 절차

A mixture of tert-butyl 1-(1-(dimethylamino)ethylideneamino)-2-methyl-1-thioxopropan-2-ylcarbamate (2.9 g, 10 mmol), hydroxylamine-O-sulfonic acid (CAN 2950-43-8, 1.37 g, 12 mmol), pyridine (1.6 g, 20.2 mmol) and methanol (4 mL) in ethanol (20 mL) was stirred at room temperature for 2 h. After evaporation of solvents, the residue was diluted with ethyl acetate (40 mL) and water (40 mL). The organic layer was washed with brine (40 mL), dried over anhydrous sodium sulfate and concentrated to give crude product (2.5 g, 96%) as yellow oil. The product was used directly in the next step without further purification; MS (EI): m/e 258.2 [M+H]+.
