To a solution of 3-{[6-(4-ethylphenyl)-3-(trifluoromethyl)-2-pyridinyl]amino}-1-propanol (Example 316) (0.34 g, 1.05 mmol) and ethyl [(1S)-5-hydroxy-2,3-dihydro-1H-inden-1-yl]acetate (Example 6, 0.18 g, 0.84 mmol) in THF (8.50 mL) was added PPh3 (0.29 g, 1.09 mmol) and ADDP (0.28 g, 1.09 mmol) under argon. The golden yellow mixture was stirred at rt for 18 h, and then concentrated under reduced pressure. The product (0.33 g, 74%) was isolated after silica gel flash chromatography (2:1 hexanes/EtOAc). 1H NMR (400 MHz, CD2Cl2) δ 7.99 (d, 2H), 7.72 (d, 1H), 7.25 (d, 2H), 7.12 (d, 1H), 7.01 (d, 1H), 6.76 (d, 1H), 6.68 (dd, 1H), 4.15 (q, 2H), 4.08 (t, 2H), 3.82 (t, 2H), 3.45 (qt, 1H), 2.90-2.68 (m, 5H), 2.42-2.28 (m, 2H), 2.16 (qt, 2H), 1.78-1.68 (m, 1H), 1.30-1.24 (m, 6H).
