Reaction Steps

To a 250 mL round bottomed flask containing 10 g (55 mmol) of 4-nitro-3-methoxybenzyl alcohol in 150 mL THF was added, diethylazodiacarboxylate (8.03 g, 54.6 mmol, 1 eq.) and triphenylphosphine (15.0 g, 57.3 mmol) followed by 11.6 g of phthalimide (57.3 mmol) at 0° C. Reaction was then allowed to gradually warm to room temperature over night. A white precipitate formed and was collected by suction filtration. Recrystallization from acetonitrile gave 13.8 g (81%) of the desired product. 1H NMR (400 MHz, d6-DMSO): δ 7.79 (m, 5H), 7.19 (s, 1H), 7.08 (d, J=8.80 Hz, 1H), 4.91 (s, 2H), 3.87 (s, 3H).
