Potassium Carbonate → N-(4-iodobenzyl)glycine tert-butyl ester

Participants

Reaction Steps

A mixture of 4-iodobenzylamine (5.0 g, 21.5 mmol), tert-butylbromoacetate (4.19 g, 21.5 mmol), potassium carbonate (3.55 g, 21.5 mmol) in 40 mL of 1:1 toluene/water was stirred at room temperature for 16 h. The reaction mixture was extracted with ethyl acetate (100 mL×3) and the combined organic phase was washed with brine, dried over sodium sulfate, and evaporated to give an oil. Chromatography on silica gel gave 2.3 g (31%) of N-(4-iodobenzyl)glycine tert-butyl ester as a colorless oil.
