実験手順

To ethyl 2-oxocyclopentanecarboxylate (4 g, 25.6 mmol) was added benzyl alcohol (3.6 g, 33.3 mmol) and the resulting mixture was heated to 175° C. for 1 hour. The reaction mixture was concentrated under reduced pressure using a high vacuum pump to yield benzyl 2-oxocyclopentanecarboxylate (5.2 g, 23.84 mmol, 93% yield) as an oil. This compound was used for the next step without further purification.
