Reaction Steps

Methyl iodide (2 mL, 32.1 mmol) was added to a mixture of 7-bromonaphthalen-2-ol (6.26 g, 28.0 mmol) and K2CO3 (4.62 g, 33.4 mmol) in DMF (21 mL). After stirring for 3 days, the mixture was partitioned between ethyl acetate/H2O and the organic solution was further washed with H2O (5×60 mL). The organic solution was then dried (Na2SO4), filtered and evaporated. Purification by flash chromatography (ethyl acetate/hexanes) gave the title compound (6.41 g, 96%).
