실험 절차

A mixture of 2-methoxynaphthalene (20,0 g, 126 mmol) and methyl pyruvate (19,3 g, 190 mmol) in dichloromethane (100 mL) was added to a suspension of aluminium chloride (25,3 g, 190 mmol) in dichloromethane (100 mL) at 6° C. over 140 minutes. The solution was stirred for a further 15 minutes at this temperature and added to ice/water. Methyl 2-hydroxy-2-(6-methoxynaphth-2-yl)propionate (52% yield) and 2-methoxynaphthalene (34% recovery) were the primary components of the reaction mixture.
