실험 절차

5-Bromonapthoic acid (J Chem. Soc., 1950, 991) (5.13 g, 20 mmol) was added to a solution of thionyl chloride (10 ml) in methanol (200 ml). The mixture was stirred at reflux for 4 h, yielding a dark brown solution. On cooling, the title compound precipitated as a light brown solid, which was filtered off and dried, yielding 5.34 g material (98%).
