Reaction Steps

5-Chloro-2-hydroxy-benzaldehyde (7 g, 45 mmol), 2-bromo-2-methyl-propionic acid ethyl ester (11.4 g, 58 mmol), K2CO3 (18.6 g, 135 mmol) and KI (0.97 g, 5.8 mmol) were mixed in DMF (20 mL). Then the reaction mixture was heated at 110° C. for 3 h. The mixture was filtered and the filtrate was concentrated. The residue was dissolved in ethyl acetate and washed with 1N NaOH. Then the organic layer was separated, dried over Na2SO4 and concentrated to give title compound (7 g)
