Procedure

To a solution of 6-hydroxy-1-tetralone (2.62 g) in acetone (50 ml) was added anhydrous potassium carbonate (2.23 g) followed by methyl bromoacetate (1.52 ml) and the resulting mixture was stirred for 18 hours. The mixture was filtered and the solvent was evaporated to give a yellow solid. Recrystallisation from ethyl acetate gave methyl tetralone-6-oxyacetate (2.28 g): NMR (d6DMSO) δ 1.95-2.05(m,2H), 2.45-2.55(m,2H), 2.9(t,2H), 3.7(s,3H), 4.9(s,2H), 6.85-6.9(m,2H), 7.8(d,1H); m/e 235(M+H)+.
