Reaction Steps

A catalytic amount of either p-toluene sulfonic acid•H2O or Bio-Rad SCX resin (analytical grade, 5.1 meq/g, AG 50W-X8) was added to □-methylstyrene (0.5 mL, 3.85 mmol) and ethylene glycol (0.21 mL, 3.85 mmol), and the reaction was stirred at rt for 5 days. The reaction mixture was loaded directly onto a SPE cartridge (10 g silica) and eluted with the following 10 mL fractions: 10% EtOAc/hexanes (fractions 1,2), 30% EtOAc/hexanes (fractions 3,4), and 50% EtOAc/hexanes (fractions 5,6) to give the title compound (30.5 mg, 4%) for both conditions. The product was characterized by 1H NMR (400 MHz) in CDCl3.
