실험 절차

To a solution of ethyl [(1S)-5-(3-{[6-(4-methoxyphenyl)-3-(trifluoromethyl)-2-pyridinyl]amino}propoxy)2,3-dihydro-1H-inden-1-yl]acetate (Example 307) (0.05 g, 0.09 mmol) in THF (1 mL), methanol (1 mL), and water (0.5 mL) was added LiOH (0.02 g, 0.85 mmol). The mixture was stirred at rt for 18 h, and then concentrated under reduced pressure. The residue was taken up in water and acidified to pH ˜5 using H3PO4 (5% aqueous solution). The aqueous solution was then extracted with EtOAc. The combined organic phases were dried (Na2SO4), filtered, and then concentrated under reduced pressure to give the product (0.034 g, 80%). 1H NMR (400 MHz, CD2Cl2) δ 8.03 (d, 2H), 7.68 (d, 1H), 7.07 (dd, 2H), 6.97 (d, 2H), 6.80 (s, 1H), 6.72 (dd, 1H), 5.37 (b, 1H), 4.11 (t, 2H), 3.91-3.81 (m, 5H), 3.56-3.48 (m, 1H), 2.95-2.77 (m, 3H), 2.15-2.37 (m, 2H), 2.23-2.18 (m, 2H), 1.65-1.55 (m, 1H).
