실험 절차

To a solution of 2-amino-5-[4-(2-morpholin-4-yl-ethoxy)-phenyl]-pyridin-3-ol (prepared according to the procedures for 2-amino-5-phenyl-pyridin-3-ol in Example I-88) (45.5 mg, 0.14 mmol) in DMF (3 mL) at 0° C. was added NaH (60% in oil) (5.6 mg, 0.14 mmol) and the mixture was stirred at 0° C. for 20 min. Then 1-Bromomethyl-3-nitro-benzene was added and the mixture was stirred at 0° C. for 1 hr and at room temperature for 2 hr. Cold 1 N aqueous HCl (0.1 mL) was added and the solvent was removed under reduced pressure. The residue was purified with silica gel chromatography (CH2Cl2:MeOH:NH4OH 100:3:0.3) to give 5-[4-(2-morpholin-4-yl-ethoxy)-phenyl]-3-(3-nitro-benzyloxy)-pyridin-2-ylamine as yellow solid (44 mg, 68%).
