실험 절차
To a 250 mL round bottom flask was added anhydrous aluminum chloride powder (21.6 g, 162.2 mmol) and 1,1,2,2-tetrachloroethane (20 mL). The resulting solution was cooled to 0° C. under Ar and then a solution of phenylacetyl isothiocyanate (12.5 g, 70.5 mmol) in 1,1,2,2-tetrachloroethane (10 mL) was added dropwise via addition funnel over a period of 10 min. Upon completion of addition, the reaction mixture was stirred at 95° C. for 1 h during which time the slurry became a dark brown solution. The reaction mixture was then allowed to cool to RT. Once at the prescribed temperature, the reaction mixture was carefully quenched with a solution of cold HCl (250 mL, 2.4 N). The resultant beige precipitate was collected by vacuum filtration, air dried for 0.5 h and then recrystallized from glacial AcOH and decolorizing charcoal to yield the title compound as an orange crystalline solid (7.2 g, 40.6 mmol, 58%). 1H NMR (400 MHz, CDCl3): δ ppm 3.29 (s, 1H), 11.78 (s, 1H), 8.57 (d, 1H, J=8.35 Hz), 7.59-LC/MS m/z [M+H].
