実験手順

A mixture of ((1R,2S)-2-hydroxycyclohexyl)methyl 4-methylbenzenesulfonate (0.334 g, 1.24 mmol), compound 58 (0.432 g, 1.54 mmol), cesium carbonate (0.562 g, 1.73 mmol) in anhydrous DMF (8 mL) was stirred at 60° C. under argon for 18 hrs, and then concentrated under reduced pressure. Water was added and the product was extracted with EtOAc three times. Combined fractions were washed with sat. NH4Cl, brine, and concentrated under reduced pressure. The residue was purified by flash chromatography (20% to 70% EtOAc/hexanes gradient) to afford 2-(3-(3-(((1R,2S)-2-hydroxycyclohexyl)methoxy)phenyl)propyl)isoindoline-1,3-dione as a colorless oil. Yield (0.191 g, 41%). 1H NMR (400 MHz, DMSO-d6) δ 7.76-7.85 (m, 4H), 7.09 (t, 7.6 Hz, 1H), 6.69-6.74 (m, 2H), 6.61-6.65 (m, 1H), 4.34 (d, J=4.1 Hz, 1H), 3.91 (dd, J=7.0, 9.2 Hz, 1H), 3.86-3.89 (m, 1H), 3.67 (dd, J=6.9, 9.2 Hz, 1H), 3.53-3.60 (m, 2H), 2.50 (t, J=7.6 Hz, 2H), 1.80-1.91 (m, 2H), 1.73-1.80 (m, 1H), 1.51-1.66 (m, 3H), 1.28-1.44 (m, 4H), 1.17-1.25 (m, 1H).
