Procedure
Hydrazine monohydrate (0.138 ml, 2.86 mmol) was added to a solution of intermediate 34 (0.80 g, 1.9 mmol) in EtOH (90 mL), and the resulting mixture was stirred at room temperature for 24 h. After filtration of a white solid, the solution was evaporated and the residue was extracted with Et2O (2×20 mL). The organic layers were filtered and evaporated to give intermediate 35 (0.520 g, 95%) as an oil, which was used for the following reaction without any further purification; 1H-NMR (CD3OI), 80 Mhz) δ 1.59 (s, 9H, 3×CH3), 1.65 (s, 6H, 2×CH3), 2.02 (m, 12H, 6×CH2), 3.27 (d, 2H, J=7.2 Hz, CH2), 5.12 (br, 3H, 3×CH), 5.25 (t, 1H, J=7.2 Hz, CH); MS (FAB+) m/e 290 (M+H)+.
