実験手順
2.15 g (5.44 mmol) of the compound obtained in step d) are dissolved in 200 ml of methanol and 0.85 g of activated 10% palladium-on-charcoal (wet) is added. The reaction mixture is hydrogenated at 60 psi for 3 hours. The solution is filtered and 1.3 equivalents (0.64 g) of oxalic acid (7.07 mmol) are added and the solution is then concentrated under vacuum. Ethanol is added, followed by ether (1:50 ratio) and a crystallized product is obtained. After filtration and washing with diethyl ether, the solid is dried under vacuum for 24 hours over P2O5 at 35° C. The desired product is obtained.
