実験手順

To a stirred solution of N—[[4-[5-(3,5-dichlorophenyl)-4,5-dihydro-5-(trifluoromethyl)-3-isoxazolyl]-1-naphthalenyl]carbonyl]glycine (i.e. the title product of Step B) (100 mg) and pyridine (0.019 mL) in dichloromethane (3 mL) was added trimethylacetyl chloride (0.029 mL). The reaction mixture was stirred at room temperature for 2 h, and then 2-methoxyethylamine (0.11 mL) and triethylamine (0.68 mL, 5.0 mmol) were added. The reaction mixture was stirred at room temperature overnight, quenched with water, extracted with dichloromethane, washed with brine, dried with anhydrous sodium sulfate and concentrated. The residue was purified by column chromatography on silica gel using hexanes/ethyl acetate (3:2 to 1:4) as eluent to afford the title compound, a compound of the present invention, as a white solid (71 mg, 0.13 mmol, 65% yield).
