Reaction Steps

To 2-bromo-3-methylpyridine (1.3 mL, 11.7 mmol) in THF (35 mL) at −78° C. was added n-BuLi (2.5 M in hexanes, 5.6 mL, 14 mmol). After 30 min, tri-n-butyltin chloride (3.8 mL, 14 mmol) was added. After 1 h at −78° C., the reaction was allowed to warm to rt. EtOAc was added and the reaction mixture was washed with 10% aq KF. The organic layer was dried (MgSO4). Purification via silica gel chromatography (0-15% EtOAc in heptane) gave the title compound (1.2 g, 27%). MS (ESI) mass calcd. for C18H33NSn, 382.2; m/z found 384.0 [M+H]+.
