Procedure
6-Hydroxy-2-naphthoic acid is heated under reflux for 2 h in anhydrous methanol which had previously been saturated with HCl gas. The mixture is concentrated, the residue is recrystallized once each from methanol and from acetone and methyl 6-hydroxy-2-naphthoate is obtained.
Workup
- concentrationThe mixture is concentrated
- customthe residue is recrystallized once each from methanol
