실험 절차

A solution of benzyl-(1-chlorocarbonyl-6,7-dimethoxy-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl)-carbamic acid ethyl ester (Example 107A) (24 mg, 0.054 mmol), 2,2,2-trifluoroethanol (0.10 mL, 1.4 mmol), and sodium hydride (56 mg, 60% dispersion in mineral oil, 1.4 mmol) in anhydrous dioxane (1 mL) was stirred at room temperature overnight. The reaction mixture was quenched with 10 mL of water and extracted with ethyl acetate (3×15 mL). The combined organic phases were washed with 10 ml of brine, dried over sodium sulfate, filtered and concentrated in vacuo to give 43 mg of an oil. Purification by silica gel chromatography using 0-50% ethyl acetate/hexanes as eluent afforded the desired final product (15 mg, 58%): MS m/z 510 (M+), 528 (M+ +18); 1H NMR (CDCl3) δ 6.99 (C8, s, 1H), 6.44 (C5, s, 1H).
