Reaction Steps

Glutarimide (5 g, 44.2 mmol) was suspended in acetone (Volume: 100 mL) and then K2CO3 (12.22 g, 88 mmol), Bu4NI (3.27 g, 8.84 mmol) and 4-methoxybenzyl chloride (6.02 mL, 44.2 mmol) were added. The mixture was agitated at room temperature overnight and filtered through celite and then concentrated in vacuo and the residue purified by flash chromatography (0-50% EtOAc/heptane) to afford 8.99 g of the desired product as a colorless solid. LCMS (m/z): (MH+), 234.2, 0.66 min.
