Reaction Steps

To a solution of methyltriphenylphosphonium bromide (2.05 g, 5.73 mmol, 2.0 equiv) in THF (10.0 mL) at −78° C. was added n-BuLi (3.58 mL, 1.6 M solution, 2.0 equiv) and stirred for 30 min followed by addition of 5,6-dihydro-5-tosylthieno[3,2-c]pyridin-7(4H)-one (880 mg, 2.86 mmol, 1.0 equiv) in THF (5.00 mL). The reaction mixture was stirred at rt for 1 h, then quenched by the addition of a saturated aqueous solution of ammonium chloride. Purification by column chromatography using 5% ethyl acetate in hexanes elution gave 175 mg of the yellow solid, 20%.
