Vorschrift

A solution of 113 (1.7 g, 5.1 mmol) in a mixture of methanol/ethyl acetate (80 and 10 mL correspondingly) was placed in a 0.5 L Parr flask and palladium on carbon (1.1 g, 5% wet. Pd/C) was added. The reaction mixture was shaken at 50 psi of hydrogen pressure at room temperature overnight. After this time, the mixture was filtered through a silica gel pad and the solvent was removed at reduced pressure to give crude 114 (1.2 g) as a brown oil. The crude 114 was used in the next step without further purification.
