In a Parr shaker bottle was placed (Z)-2-benzyloxycarbonylamino-3-(trans-3-methyl-cyclobutyl)-acrylic acid methyl ester (300 mg, 0.99 mmol), methanol (10 mL) and 10% palladium on activated carbon (60 mg). The mixture was placed on the Parr hydrogenator and charged with 40 psi hydrogen pressure and shaken for 1.5 h. After such time, the catalyst was filtered off through a plug of celite and the filterate concentrated in vacuo to afford 2-amino-3-(trans-3-methyl-cyclobutyl)-propionic acid methyl ester (148 mg, 87%) as a pale yellow oil.
