N,N-diisopropylethylamine (0.745; 4.33 mmol) was added to a mixture of 2-(5-chloro-1H-indol-3-yl)ethanamine hydrochloride (0.500 g; 2.16 mmol), and phenyl chloroformate (0.406 mL; 3.25 mmol) in dichloromethane (20 mL). The solution was stirred at room temperature for 20 minutes, diluted in dichloromethane, washed with sodium hydrogen sulfate (1M, water), sodium carbonate (1M, water) and brine. The organic layer was dried and concentrated under reduced pressure to furnish 0.60 g (88%) of phenyl 2-(5-chloro-1H-indol-3-yl)ethylcarbamate as a yellow oil.
