Participants

Reaction Steps

Into 300ml of glacial acetic acid there was stirred 11.7g (0.1 moles) of dl-valine. 13.8g of sodium nitrite was added, with stirring, over the duration of 1 hour and the temperature of the reaction medium maintained at room temperature by means of a water bath. After the mixture had been stirred overnight at room temperature, the acetic acid was evaporated off and water (50ml) added. Solvent extraction using diethyl ether then followed. The diethyl ether portion was washed with water, dried over anhydrous magnesium sulphate and the ether evaporated off to yield 12.2g of the title product as a colourless oil.
