Reaction Steps
To solution of 2-ethyl-4-methoxyaniline (4.5 g, 30 mmol) and triethylamine (6.0 g, 60 mmol) in dichloromethane (31 mL) was added thiophosgene (3.4 g, 30 mmol) was added drop wise at 0° C. over the period of 1 hour. After completion, the reaction mixture was poured into ice-water (100 mL) and extracted with ethyl acetate (3×200 mL) and washed with ice water (2×100 mL), followed by brine (2×50 mL). The organic phase was dried over sodium sulfate, filtered, and evaporated under reduced pressure. Purification by flash column chromatography using 0-10% ethyl acetate/hexanes as eluent provided 2-ethyl-1-isothiocyanato-4-methoxybenzene as yellow oil (4.9 g, 25 mmol), which was taken onto the next step immediately.
