3-METHOXY-2-NAPHTHOL 97

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Dimethylsulfate (32 ml) was added to the solution of 2,3-dihydroxynaphthalene (32 g) and sodium hydroxide (10 M, 32 ml) in water (300 ml). After being stirred for six hours at room temperature, the side product 2,3-dimethoxynaphthalene was filtered off (yield 16.6 g). The water phase was acidified, stirred on ice bath, filtered, washed with water and recrystallized from ethanol-water (3:2). Yield: 13.5 g, melting point 108-109° C. the side product 2,3-dimethoxynaphthalene was filtered off (yield 16.6 g) stirred on ice bath filtered washed with water recrystallized from ethanol-water (3:2)
