실험 절차

Treat a solution of the product of step 2 (13.2 g, 65 mmol) in CH2 Cl2 (250 mL) at 0° C. with pyridine (7.89 mL, 97.5 mmol, 1.5 eq) and dimethylaminopyridine (397 mg, 3.25 0.05 eq), followed by CH3COCl (6.48 mL, 74.75 mmol, 1.15 eq). Allow the mixture to warm to 23° C., pour into 1M HCl (100 mL) and wash the resulting organic layer again with 1M HCl (100 mL), followed by water (5×100 mL; pH=6.5-7). Dry the organic layer (Na2SO4) and concentrate to obtain 15.4 g (62.9 mmol, 97%) of 3-(3,4-dichlorophenyl)-2-propene-1-ol acetate as a colorless oil.
