Reaction Steps
To a solution of O-protected pyridine dimethylcarbinol (3.0 g, 10.6 mmol) in THF (50 mL) at −78° C. was added n-BuLi 2.5 N in hexanes (4.7 ml, 11.7 mmol) followed, 1 min later, by phenylthionochloroformate (2.76 g, 16.0 mmol). The reaction was stirred at −78° C. for 40 min, then allowed to warm to RT and stirred 4 h. The final mixture was treated with saturated NaHCO3, extracted with DCM and AcOEt and combined organic layers were dried over Na2SO4 and concentrated. Purification of the residue by flash chromatography over silica gel (eluting hexane to DCM) afforded 1.5 g of O-protected pyridine propene as well as 1.8 g of starting O-protected pyridine dimethylcarbinol.
