Reaction Steps
To 2-chloro-4-hydroxy-benzoic acid hydrate (1.1 g) in DMF (20 mL) was added K2CO3 (2.4 g) and methyl iodide (0.75 mL). After 2 h, water was added to the reaction mixture and extracted with ethyl acetate. The organic layer was washed with brine (3×) and dried over MgSO4. Flash chromatography on silica gel eluting with 10% ethyl acetate-hexane afforded 1.13 g (95%) of the title compound as an oil. MS: 201 (MH+), HPLC tR: 2.52 min.
