Procedure

A mixture of N-(3-hydroxy-benzyl)-methanesulfonamide (6.000 g, 29.82 mmol), methyl bromoacetate (4.562 g, 29.82 mmol), K2CO3 (4.121 g, 29.82 mmol), and acetone (250 mL) was stirred at room temperature for 68 h. The solids were removed by filtration and the solution was concentrated in vacuo. Purification by flash chromatography (1:1 hexanes:EtOAc) provided the title compound (5.637 g). 1H NMR (400 MHz, CDCl3) δ 7.25 (m, 1H), 6.96 (m, 1H), 6.89 (s, 1H), 6.82 (m, 1H), 4.63 (m, 3H), 4.28 (m, 2H), 3.80 (s, 3H), 2.86 (s, 3H); MS 274 (M+1).
