Versuchsvorschrift

A mixture of 12-1 (400 mg, 1.0 mmoles), 10% Pd/C (160 mg), and CH3OH (5 mL) was stirred at ambient temperature under a hydrogen atmosphere for 3.0 hours. The reaction mixture was filtered through a celite pad and the filtrate concentrated to give 12-2 as a yellow oil. Rf 0.33 (silica, 30% EtOAc/hexanes).
