Versuchsvorschrift
A mixture of benzyl N-t-butoxycarbonyl-4-(3-methylbenzyl)-isonipecotate (2.36 g, 5.57 mmol), 5% palladium on charcoal (250 mg), and glacial acetic acid (3 mL) in methanol (75 mL), was hydrogenated at 50 psi. in a Parr shaker at room temp. overnight. The reaction mixture was filtered through a pad of Celite and the filtrate was concentrated under vacuum to provide the title product as white solid.
