실험 절차
Hydrazine hydrate (1.36 mL, 43.3 mmol) was added to a solution of 2-(3-tert-Butoxy-propoxy)-isoindole-1,3-dione (6.0 g, 21.7 mmol) in CH2Cl2 (50 mL) with MeOH (5 mL), and the reaction stirred 1 h at room temperature. The precipitate was removed by filtration, and the filtrate was purified by silica gel chromatography (6% MeOH/CH2Cl2) to give 2.4 g (75%) of compound 29A as a clear oil. 1H NMR (400 MHz, CDCl3): δ 4.94 (br s, 2H), 3.71 (t, 2H, J=6.4 Hz), 3.38 (t, 2H, J=6.4 Hz), 1.70-1.79 (m, 2H), 1.15 (s, 9H).
