실험 절차
To a solution of 10 g Benzene-1,2-diamine in 250 mL acetic acid, 22.8 g 2,2,2-Trichloro-acetimidic acid methyl ester were added drop wise at RT. After 2 h 500 mL toluene were added and the solvents were removed under reduced pressure. The residue was codestilled additional two times with toluene. After drying under reduced pressure the product was pure enough for the next reaction step.
