実験手順

To a solution of 100 mg (0.30 mmol) of methyl (2S)-3-(4-hydroxyphenyl)-2-[(phenylmethoxy)carbonylamino]propanoate, as prepared in the preceding step, 67 mg (0.30 mmol) of 2-(3-hydroxypropoxy)isoindoline-1,3-dione, as prepared in step 2, and 88 mg (0.34 mmol) of triphenylphosphine in 10 mL THF at water/ice mixture temperature was added 66 mL (0.34 mmol) of DIAD dropwise. The solution was stirred at the same temperature for additional 20 min. Then the solution was allowed to warm to room temperature and stirred overnight. The solvent was removed under reduced pressure. The mixture was chromatographed on a silica gel column using EtOAc/hexanes (3:7 to 2:3 v/v) as eluent to yield 89 mg (55%) of viscous liquid as product: 1H NMR (300 MH, CDCl3) δ7.85-7.80 (m, 2H), 7.77-7.71 (m, 2H), 7.38-7.27 (m, 5H), 6.98 (d, J=8.65 Hz, 2H), 6.82 (d, J=8.65 Hz, 2H), 5.19 (d, J=8.16 Hz, 1H), 5.09 (s, 2H), 4.61 (m, 1H), 4.40 (t,J=6.22, 2H), 4.19 (t, J=6.11 Hz, 2H), 3.71 (s, 3H), 3.08-2.96 (m, 2H), 2.23 (quintet, J=6.15 Hz, 2H).
