4-Methylmorpholine → HCID 69266479, 화합물

To a solution of 3-methyl-N-(2,2-diphenylacetyl)-L-phenylalanine (1.0 g, 2.68 mmol) and O-[[3-(methoxycarbonyl)phenyl]methyl]-L-serinamide HCl (0.774 g, 2.68 mmol), 1-hydroxybenzotriazole hydrate (0.452 g, 2.95 mmol, and N-methylmorpholine (1.18 mL, 1.085 g, 10.72 mmol) in CH2Cl2 (50 mL) is added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide HCl (0.771 g, 4.02 mmol) in one portion and the mixture is stirred at room temperature for 16 hours. The solution is then washed with 1 N HCl (100 mL), saturated aqueous NaHCO3 (1×50 mL), water (1×50 mL) and brine (1×50 mL), dried over MgSO4, and evaporated. The residual solid is triturated with hot methanol to yield N-[3-methyl-N-(2,2-diphenylacetyl)-L-phenylalanyl]-O-[[3-(methoxycarbonyl)phenyl]methyl]-L-serinamide as a white solid.
