Reaction Steps

A mixture of m-nitrophenylglycine (58.0 g, 0.296 mol), MgO (23.92 g, 0.6 mol) and t-butoxylcarbonyl azide (85.2 g, 0.6 mol) in 50% aqueous dioxane (700 ml) was heated at 45° for 17 hours. The reaction was cooled, water (750 ml) was added and the mixture was filtered. The filtrate was washed with ether (1000 ml), acidified to pH 3 with 40% H3PO4, and extracted with ethyl acetate. The dried extracts were evaporated to give α-t-butoxycarbonylamino-m-nitrophenylacetic acid (70.3 g).
