Procedure

Sodium hydride (0.02 g, 0.86 mmol) was added to a solution of ethyl [(1S)-5-(3-{[6-(4-ethylphenyl)-3-(trifluoromethyl)-2-pyridinyl]amino}propoxy)-2,3-dihydro-1H-inden-1-yl]acetate (Example 318) (0.21 g, 0.39 mmol) in DMF (2 mL). After stirring at rt for 30 min, MeI (0.05 mL, 6.32 mmol) was added. The mixture was stirred at rt for 18 h, quenched with water (5 mL), and extracted with ether (3×). The combined ether extracts were washed with water and brine, dried (MgSO4), filtered, and concentrated under reduced pressure. The product (0.017 g, 8%) was isolated after silica gel flash chromatography (2:1 hexanes/EtOAc). 1H NMR (400 MHz, CD2Cl2) δ 7.99 (d, 2H), 7.85 (d, 1H), 7.35-7.25 (m, 3H), 7.01 (d, 1H), 6.72 (d, 1H), 6.65 (dd, 1H), 4.15 (q, 2H), 4.00 (t, 2H), 3.73 (t, 2H), 3.47 (qt, 1H), 3.08 (s, 3H), 2.90-2.68 (m, 5H), 2.42-2.30 (m, 2H), 2.15 (qt, 2H), 1.78-1.68 (m, 1H), 1.32-1.26 (m, 6H).
