Reaction Steps

According to the same procedure as described in Example 2, using 20.8 g (100 mmol) of 2-hydroxy-4-phenylbutyric acid ethyl ester, methylene chloride (50 ml), 72.6 g (purity 12.3%, 120 mmol) of sodium hypochlorite, 43 mg (0.2 mmol) of 4-acetoxy-2,2,6,6-tetramethylpiperidinyl-1-oxy, and 10 ml (10 mmol) of 1N sulfuric acid, was obtained 18.95 g of 2-keto-4-phenylbutyric acid ethyl ester. The yield was 92%.
