実験手順

(2S,4R)-(4-{Acetyl-[1-(4-methoxybenzoyl)-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl]-amino}-phenoxy)-acetic acid was prepared from (2S,4R)-(4-{acetyl-[1-(4-methoxybenzoyl)-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl]-amino}-phenoxy)-acetic acid methyl ester (15 mg, 0.03 mmol). The methyl ester was dissolved in methanol (1 mL), sodium hydroxide (1 mL, 0.1 M in water) was added and the resulting solution was stirred at room temperature for 18 h. The reaction mixture was acidified with hydrochloric acid (1 M) and concentrated under reduced pressure. The residue was extracted with ethyl acetate and the extract was washed thrice with water, brine, dried over sodium sulphate, filtered and concentrated to yield the title compound (13 mg, 89%).
