Reaction Steps

To a stirred solution of Example 8D (0.03 g, 0.153 mmol ) and potassium carbonate (0.2 g, 1.53 mmol) in acetonitrile (2 mL ), at room temperature under nitrogen was added R(+)-3-aminotetrahydrofuran toluene-4-sulfonate (0.08 g, 0.32 mmol ). The reaction mixture was stirred overnight and then concentrated under reduced pressure. The residue was flash chromatographed with 2% MeOH/CH2Cl2 to provide the desired compound as a pale yellow oil. MS (DCI) m/z 248 (M+H)+; 1H NMR (300 MHz, DMSO-d6) δ 1.5-2 (2H, m), 2.11-2.21 (2H, m), 2.45-2.48 (2H, m), 3.78 (1H, d), 3.8-4.5 (2H, m), 4.53-4.55 (1H, t), 5.01 (1H, m), 5.05 (1H, m), 5.43-5.9 (4H, m).
