실험 절차

To a solution of ethyl [(1S)-5-(2-hydroxyethoxy)2,3-dihydro-1H-inden-1-yl]acetate (Example 249, 50.0 mg, 0.19 mmol) and 2,6-dimethylpyridin-3-ol (46.6 mg, 0.38 mmol) in THF (1.5 mL) were added PPh3 (99.2 mg, 0.38 mmol) and ADDP (95.5 mg, 0.38 mmol). The reaction mixture was vigorously stirred at rt for 24 h, and then directly applied to a silica gel column for purification (1:1 hexanes/EtOAc) to give the product (58.9 mg, 84%) as a colorless oil. 1H NMR (400 MHz, CDCl3) δ 1.29 (t, 3H) 1.72-1.81 (m, 1H), 2.36-2.2.44 (m, 2H), 2.45 (s, 3H), 2.47 (s, 3H), 2.73 (dd, 1H) 2.82-2.92 (m, 2H), 3.52-3.56 (m, 1H) 4.19 (q, 2H), 4.26-4.33 (m, 4H), 6.75 (d, 1H), 6.82 (s, 1H) 6.92 (d, 1H), 7.05 (d, 1H), 7.08 (d, 1H).
