Versuchsvorschrift

After the addition of anhydride THF (20 ml) to compound 5d (1.40 g, 7.34 mmol), the temperature was adjusted to 0° C. Diethyloxalate (1.45 g, 9.50 mmol) and potassium t-butoxide (1.35 g, 11.9 mmol) were added thereto and the agitation for 3 hours was carried out. After the identification of the reaction progress with TLC, the solution was poured into the distilled water and acidified with 1N HCL aqueous solution. Three times extractions were carried out with EA and three times washings were carried out with brine. Water was removed by using Na2SO4 and solvents were removed. Crude purification was carried out by the column chromatography but the next reaction was followed since the purified compound was small in quantity.
