実験手順

A mixture of (S)-4-(1-benzyl-2-trityloxy-ethylamino)-3-[6-bromo-4-methyl-1H-benzimidazol-2-yl]-1H-pyridin-2-one (150 mg, 0.216 mmol), morpholine (28.2 mg, 0.324 mmol), palladium acetate (2.4 mg, 0.01 mmol), tri-tert-buylphosphine (4.4 mg, 0.02 mmol), and sodium tert-butoxide (104 mg, 1.08 mmol) in toluene (5 mL) was heated to 100° C. for 14 h under nitrogen. The reaction mixture was cooled to room temperature and diluted with EtOAc. After extraction, the combined organic layers were washed with water, brine, dried over Na2SO4. Concentration gave a brownish residue, which was treated with 4 N HCl dioxane solution (3 mL) at room temperature for 6 h. After removal of the solvent, the residue was purified by prep.
