Reaction Steps

To a solution of the above alcohol (410 mg, 1.80 mmol) in DMF (5 mL) was added NaH (60%, 108 mg, 2.70 mmol). After 1 h, MeI (0.23 mL, 3.60 mmol) was added. After 1.5 h, the reaction mixture was filtered and the filtrate was concentrated to afford an orange oil. Purification by flash column chromatography using hexanes/EtOAc (2:1) afforded 2-bromo-3-(1-methoxy-cyclobutyl)-pyridine as a pale yellow solid (308 mg, 71%). 1H NMR (CDCl3) δ 1.61-1.71 (m, 1H), 2.04-2.14 (m, 1H), 2.56 (t, 4H, J=7.5 Hz), 2.96 (s, 3H), 7.25-7.30 (m, 1H), 7.64 (dd, 1H, J=7.5, 2.1 Hz), 8.31 (dd, 1H, J=4.7, 1.8 Hz).
