실험 절차

A solution of 2-chloro-4-(1-(2-(7-methoxyquinolin-4-yloxy)ethyl)-6-oxo-1,6-dihydropyridazin-3-yl)benzoic acid (494 mg, 1093 μmol), DIEA (191 μL, 1093 μmol), and HATU (416 mg, 1093 μmol) in DMF (5 mL) was stirred at 23° C. for 15 minutes. This dark solution was then added to a second solution of ethylenediamine (730 μL, 10933 μmol) in DMF (2 mL). The reaction was then stirred overnight at 23° C. followed by a partition between 9:1 CHCl3/IPA (75 mL) and NaOH (1 M, 25 mL). The organic was separated, dried over MgSO4, then concentrated onto dry silica (15 g). The product was purified on silica (40 g) eluting with 10% 2 M NH3 in MeOH/DCM, and isolated as a fluffy lyophilized solid from 1:1 ACN/water.
