Reaction Steps

To 65F (1.51 g, 3.53 mmol) in EtOAc (15 mL) at rt was added 4.0 N HCl in dioxane (15 mL, 60 mmol). The mixture was stirred at rt for 8.0 h. After removal of the solvent, the crude was diluted in methylene chloride and washed with sat. NaHCO3. The aqueous was extracted with methylene chloride (3×80 mL). The combined organic layer was dried over Na2SO4. After removal of solvent 65G (1.1 g, 95% yield) was obtained as viscous oil. 1H NMR (400 MHz, Methanol-d4) δ ppm 1.15 (t, J=7.03 Hz, 3H) 1.25 (d, J=7.03 Hz, 3H) 1.30 (d, J=7.03 Hz, 3H) 2.11-2.38 (m, 2H) 3.00-3.12 (m, 1H) 3.24-3.29 (m, 1H) 3.36-3.47 (m, 1H) 3.53-3.64 (m, 1H) 4.02-4.14 (m, 2H) 7.58 (dd, J=7.91, 4.83 Hz, 1H) 8.32 (dd, J=8.35, 1.76 Hz, 1H) 8.83-8.93 (m, 1H); LC-MS 327 (M+H).
