Reaction Steps

To a solution of N-Boc-glycine (175 mg) in tetrahydrofuran (2 mL), N-methylmorpholine (165 μL) and isobutyl chloroformate (131 μL) were added under ice cooling, and the mixture was stirred at the same temperature for 40 minutes. To the reaction mixture, 2-(4-bromophenyl)ethylamine (100 μL) was added under ice cooling, and the mixture was stirred at room temperature for 5 hours. To the reaction mixture, saturated aqueous sodium hydrogencarbonate and ethyl acetate were added. The organic layer was separated, and dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure to obtain tert-butyl (2-((4-bromophenethyl)amino)-2-oxoethyl)carbamate (R5).
