実験手順
To a suspension of N-[(2,6-dichlorophenyl)carbonyl]-4-[1,6-dimethyl-4-(trifluoromethyl)-2-oxo-3-pyridinyl]-L-phenylalanine (145 mg, 0.275 mmol) and sodium bicarbonate (185 mg, 2.2 mmol) in DMF (2 mL) was added iodoethane (343 mg, 2.2 mmol) at room temperature. The mixture was stirred for 72 h at room temperature. Then, the reaction mixture was poured into water (30 mL) and was extracted with ethyl acetate (3×20 mL). The combined organic extracts were washed with brine solution (60 mL) and were dried over anhydrous magnesium sulfate. Filtration of the drying agent and concentration of the filtrate gave 129 mg (85% yield) of N-[(2,6-dichlorophenyl)carbonyl]-4-[1,6-dimethyl-4-(trifluoromethyl)-2-oxo-3-pyridinyl]-L-phenylalanine ethyl ester as a crystalline white solid: mp 86-91° C. ES-HRMS m/e calcd for C26H23Cl2F3N2O4 (M+Na) 577.0876. found 577.0887.
