Versuchsvorschrift

A mixture of the methyl 4-formylnaphthoate above (2.3 g, 1 mmol) and Na2CO3 (1.25 g, 12 mmol) in water (30 mL) was heated in a water bath for approximately 2 hr until a clear solution was obtained. The solution was cooled and filtered. The filtrate was acidified with conc. HCl to give a yellow precipitate. The solids were collected and dried over night to give the desired product (1.86 g, 87%).
