Reaction Steps

5-bromo-6-chloro-3-(1-BOC-2-(R)-pyrrolidinylmethoxy)pyridine from step 69a (150 mg) was stirred with HCl in dioxane (3 mL) at room temperature for 16 hours. The precipitate formed was triturated with Et2O, and the solid was dried under high vacuum to afford the title compound (99.2 mg). mp 230° C. MS (CI/NH3) m/z 291/293 (M+H)+. 1H NMR (D2O, 300 MHz) δ: 1.89-2.02 (m, 1h), 2.05-2.21 (m, 2H), 2.21-2.35 (m, 1H), 3.42 (t, J=7.2 Hz, 2H), 4/12 (m, 1H), 4.25 (dd, J=7.8, 10.5 Hz, 1H), 4.47 (dd, J=3.2, 10.5 Hz, 1H), 7.90 (d, J=2.7 Hz, 1H), 8.13 (d, J=2.7 Hz, 1H). Anal. Calcd for C10H12N2OBrCl.2 HCl: C, 36.61; H, 3.99; N, 8.54. Found: C, 36.69; H, 3.91; N, 8.41. [α]25D=−14.80° (c 0.25, MeOH).
