| Product | H-Asp(OtBu)-Leu-OH | HCID 131721134 | 89.7% |
Reaction Steps
The Z-Asp(OtBu)-Leu-OBzl (15.6 g) in methanol (50 mL) was added 10% Pd on carbon (0.17 g) and was hydrogenated on a Paar Shaker. After filtering off the catalyst, the filtrate was concentrated to give a foamy solid. The crude product was triturated with diethyl ether to yield 8.03 g of H-Asp(OtBu)-Leu-OH.
