실험 절차

To a solution of 2.18 g (11.55 mmol) of 3-tert-Butoxycarbonylamino-propionic acid in 20 ml of DMF were added 3.78 g (11.55 mmol) TOTU. After 15 min at room temperature 2.0 g (11.55 mmol) of 2-methyl-quinoline-4,6-diamine and 2.66 g (23 mmol) of N-ethylmorpholine were added. After 24 h stirring at room temperature the solution was evaporated and the residue was treated with a saturated aqueous solution of NaHCO3. The aqueous solution was extracted with ethyl acetate. The separated organic layer was dried (Na2SO4) and evaporated. The residue was treated with 20 ml 90% trifluoroacetic acid for 2 h. After evaporation the residue was dissolve in water and extracted with ethyl acetate. The aqueous layer was lyophilized to yield 5.15 g (76%) of the title compound. MS 245.1 (M+)+.
