Reaktionsschritte
A mixture of methyl 2-(benzyloxycarbonylamino)-3-(1-methylcyclohexyl)propanoate, 10.00 g of KOH, 100 mL of MeOH, and 20 mL of water was vigorously stirred at rt for 17 h. After methanol was evaporated under reduced pressure, the residue was diluted with water and extracted with Et2O (2×). The aqueous phase was treated with 100 mL of 2 NHCl, extracted with EtOAc (3×), and dried over Na2SO4. The extracts were evaporated under reduced pressure to afford 1.5150 g (36% in two steps) of 2-(benzyloxycarbonylamino)-3-(1-methylcyclohexyl)propanoic acid. MS ESI +ve m/z 320 (M+H).
