Reaction Steps

To a solution of ethyl [(1S)-5-(3-{[6-(4-methoxyphenyl)-5-(trifluoromethyl)-2-pyridinyl]amino}propoxy)-2,3-dihydro-1H-inden-1-yl]acetate (Example 304, 0.05 g, 0.09 mmol) in a mixture of 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 with 5% H3PO4. The aqueous solution was extracted with ethyl acetate. The combined organic phases dried (Na2SO4), filtered, and concentrated under reduced pressure to give the product (0.038 g, 88%). 1H NMR (400 MHz, CD2Cl2) δ 7.65 (d, 1H), 7.35 (d, 2H), 7.05 (d, 1H), 6.92 (d, 2H), 6.73 (s, 1H), 6.66 (dd, 1H), 6.49 (d, 1H), 4.02 (t, 2H), 3.84 (s, 3H), 3.55 (t, 3H), 3.45 (qt, 1H), 2.92-2.65 (m, 3H), 2.40-2.30 (m, 2H), 2.10-2.02 (m, 2H), 1.80-1.68 (m, 1H); LC-MS: RT=3.02 min, (M+H)+ 531.1.
