Reaction Steps

Sodium ethoxide (1.8 g, 26.4 mmol) was added portionwise at 0° C. to a stirred solution of 2-hydroxy-3-(3-nitrophenyl)acrylic acid (5.25 g, 25.0 mmol) in methanol (131 ml) to form a clear, pale yellow solution. Sodium borohydride (1 g, 26.4 mmol) was then carefully added in two portions and the mixture stirred at 5-10° C. for 30 mins. A small amount of water was then added to quench the reaction and destroy any excess NaBH4. The methanol was removed in vacuo to give a solid residue, which was ground with a 5:2 mixture of ethyl acetate and heptane (21 ml) then further ground with 3% aqueous methanol. The resulting solid was collected by filtration and dried in vacuo to give 2-hydroxy-3-(3-nitrophenyl)propionic acid (3.0 g, 57%).
