Procedure

To a solution of 1,6-dioxaspiro[2.5]octane (600 mg, 5.26 mmol) in methanol (10 ml) at 0° C. (ice-water) under nitrogen was added camphorsulfonic acid (50 mg, 0.21 mmol) and the resulting mixture was stirred at about 0° C. for 2 hours. The mixture was concentrated in vacuo and the crude residue was used in the next step without purification. The desired product was obtained as a light yellow oil (707 mg).
