실험 절차

3.2 grams of α-benzamido-cinnamic acid were dissolved in 40 ml of absolute ethanol and treated with 0.3 ml of the catalyst solution produced in Example 19. The reaction mixture was sucked into a 100 ml autoclave. It was pressurized with 6 bars of hydrogen pressure. After taking up the theoretical amount of hydrogen it was worked up as customary (e.g. see Example 6). There were isolated 3.15 grams of N-benzoyl-(R)-phenylalanine having the rotary value of [α]D27 =+38.6° (c=1/CH3OH), corresponding to an optical yield of 95.8%.
