Reaction Steps
A solution of 10% aqueous potassium hydroxide (150 mL) was added to a solution of 2-chloro-3-methyl-1,4-naphthoquinone (10.3 g) in refluxing methanol (500 mL). After cooling and acidification with concentrated hydrochloric acid, the precipitated product was collected by filtration to give 2-hydroxy-3-methyl-1,4-naphthoquinone, m.p. 173°-174° C.
