실험 절차

1,4-xylylene glycol (5 g, 0.0306 mol), pyridine (5.7 g, 0.072 mol), and catalyst DMAP (ca. 100 mg) in a solution of dichloromethane (ca. 25 ml) were added to a flask. Isobutyryl chloride (7.71 g, 0.072 mol) was then added to the solution drop wise. The mixture was stirred overnight. 1M HCL brine was used to wash the mixture. The organic layer was dried over MgSO4 and concentrated in vacuo to afford a clear oil as the product (9 g). Its purity was ascertained using 1H NMR (300 MHz in CDCL3): δ 7.34 (s, 4H), 5.11 (s, 4H), 2.60 (sept, 2H), 1.19 (d, 12H).
