Reaction Steps

A solution of pyruvic acid and p-fluorobenzaldehyde (24.8 g) in methanol (20 ml) was cooled to 15° C. and treated with a solution of potassium hydroxide (16.8 g) in (50 ml) methanol. After 2/3 of the addition was complete, the cooling bath was removed and the temperature was allowed to rise to 40° C. A yellow precipitate appeared and was filtered after standing overnight. The solid was washed well with methanol and ether. The title compound (34.5 g) was used without further purification.
