실험 절차
(3-Bromo-quinolin-6-yloxy)-methylsulfanyl-acetic acid (23 g) from Example 1, Stage 1 above, 2-amino-2-methyl-1-propanol (8.06 ml), 1-hydroxy-7-azabenzotriazole (HOAT) (11.44 g), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (EDC) (16.12 g) and triethylamine (14.63 ml) in dry DMF (175 ml) were stirred at rt for 16 hours. The reaction mixture was diluted with ethyl acetate and poured into 200 ml sat. NaHCO3. The two phases were separated and the aqueous layer was extracted three times with ethyl acetate (3×200 ml). The organic layers were combined, dried over magnesium sulphate, filtered and evaporated. The residue was purified by column chromatography (heptane/ethyl acetate 7:13) to give 2-(3-bromo-quinolin-6-yloxy)-N-(2-hydroxy-1,1-dimethyl-ethyl)-2-methylsulfanyl-acetamide as a white solid (16.94 g). 1H NMR (DMSO) δ ppm: 8.82 (1H, d); 8.57 (1H, d); 7.99 (1H, d); 7.58 (1H, dd); 7.52 (1H, s); 7.44 (1H, d); 5.94 (1H, s); 4.99 (1H, t); 3.48-3.37 (2H, m); 2.15 (3H, s); 1.28 (3H, s); 1.26 (3H, s).
