실험 절차

8-(Benzyloxy)-5-(6-(tert-butoxycarbonylamino)hexylamino)-1,6-naphthyridine-7-carboxylic acid (Example 1.2; 0.42 g; 0.85 mmol) was dissolved in dichloro methane (9 ml). DIPEA (0.58 ml; 3.42 mmol) and HBTU (0.39 g; 1.03 mmol) were added. The reaction mixture was stirred at room temperature during 5 min. Ethyl 2-(aminomethyl)-5-fluorobenzoate hydrochloride (Example 4; 0.24 g; 1.03 mmol) was added portionwise at room temperature. The mixture was stirred overnight at room temperature. The mixture was diluted with CH2Cl2 and washed with a saturated aqueous Na2CO3 solution (2×) and H2O. The organic layer was separated, dried (MgSO4), filtered and evaporated. The residue was purified by flash column chromategraphy over silica gel (eluent: hexane/EtOAc 10:1 up to 1:1). The fractions were collected and the solvent evaporated.
