Reaction Steps
DEAD (1.094 g, 6.286 mmol) was added drop wise to a solution of 4-(2-hydroxyethyl)-N-(4-methoxybenzyl)nicotinamide (I-65d: 1.5 g, 5.238 mmol) and PPh3 (2.784 g, 10.477 mmol) in THF (40 mL) at 0° C. and the resulting reaction mass was stirred at room temperature for 1 hour. The reaction was monitored by TLC (10% methanol in CHCl3). The reaction mass was concentrated under reduced pressure and the crude residue was purified by column chromatography on silica gel (3% methanol in DCM) to afford 700 mg of the product (49.82% yield).
