Versuchsvorschrift

3-(2-Hydroxyethyl)-N-(4-methoxybenzyl)isonicotinamide (220 mg, 0.769 mmol) was reacted with PPh3 (403 mg, 1.538 mmol), DEAD (0.15 mL, 0.922 mmol) and THF (10 mL) to afford the crude product. Purification by column chromatography on silica gel (1% methanol in CHCl3) afforded 300 mg of the product. LCMS: 66.95%, m/z=269.0 (M+1)
