실험 절차

To a solution of 2-(6-chloro-2-pyridinyl)ethanol (Example 470, 250 mg, 1.59 mmol) and ethyl [(1S)-5-hydroxy-2,3-dihydro-1H-inden-1-yl]acetate (Example 6, 698 mg, 3.17 mmol) in THF (4 mL) were added PPh3 (832 mg, 3.17 mmol) and DIAD (641 mg, 3.17 mmol). The reaction mixture was vigorously stirred at rt for 24 h, concentrated under reduced pressure, and the residue was purified by silica gel chromatography (6:1 hexanes/EtOAc) to give the product (170 mg, 30%). 1H NMR (400 MHz, CDCl3) δ 1.28 (t, 3H), 1.72-1.77 (m, 1H), 2.34-2.43 (m, 2H), 2.71 (dd, 1H), 2.81-2.89 (m, 2H), 3.21 (t, 2H), 3.51-3.52 (m, 1H), 4.17 (q, 2H), 4.31 (t, 2H), 6.69 (d, 1H), 6.76 (s, 1H), 7.04 (d, 1H), 7.19 (dd, 2H), 7.57 (t, 1H).
