Reaction Steps

A stirred solution of (methoxymethyl)triphenylphosphonium chloride (2.79 g, 8.13 mmol) in THF (50 mL) at 0° C. was treated dropwise with n-BuLi (1.6-M in hexanes, 5.08 mL, 8.13 mmol), stirred for 1 h, treated with a solution of 6-(triphenylmethoxy)methylpyridine-2-carboxaldehyde (1.54 g, 4.06 mmol) in THF (15 mL) and allowed to warm to room temperature overnight. The reaction was treated with saturated NH4Cl solution (5 mL), diluted with water (50 mL), extracted with EtOAc (2×50 mL) and the combined organic phase diluted with iso-hexane (50 mL), dried (MgSO4), filtered through silica and concentrated in vacuo to give 2-(2-methoxyethenyl)-6-(triphenylmethoxy)methylpyridine (1.58 g) as a yellow oil. A solution of this crude alkene and 10% Pd/C (216 mg, 0.203 mmol) in EtOAc (50 mL) was stirred under a hydrogen atmosphere for 16 h, filtered through Celite and concentrated in vacuo to give the title compound (1.08 g, 65%) as a yellow oil; NMR δH (400 MHz, CDCl3) 7.67–7.64 (1H, m), 7.52–7.49 (6H, m), 7.32–7.21 (10H, m), 7.09–7.07 (1H, m), 4.34 (2H, s), 3.69 (2H, t, J 6.5 Hz), 3.32 (3H, s) and 2.98 (2H, t, J 6.5 Hz); M/Z 410 (M+H)+.
