Reaction Steps

A solution of 35.6 g of sodium nitrite in 100 ml of water was added to a cold solution of t-butyl 4-chloro-3-oxobutanoate (100.9 g, 0.439 moles of 84% material*)inin 400 ml of acetic acid containing 50 ml of water over a 0.5 hour period with stirring. The mixture was stirred in the cold for an additional hour, then stored in the cold overnight. The mixture was diluted with 500 ml portions of water, 500 ml of saturated sodium bicarbonate, 500 ml of water and 500 ml of brine, then dried over magnesium sulfate and evaporated to give an amber oil; yield 88.6 g (91% yield). This material was used in the next step without further purification.
