Reaction Steps

A solution of 1-bromo-5-dimethoxymethyl-2-(2-morpholinoethoxy)benzene (3.11 g, 8.63 mmol) obtained in Step 3 in THF (40.0 mL) was cooled to −78° C., to which n-butyllithium (1.60 mol/L, 20.0 mL, 32.0 mmol) was added dropwise for 3 minutes, followed by stirring at −78° C. for 5 minutes. The reaction mixture was added with dry ice and was stirred for 3 hours while warming to room temperature. The solvent of the reaction mixture was evaporated under reduced pressure. The residue was added with a 1 mol/L aqueous ammonium acetate solution (30 mL), was purified by HP-20 column chromatography (water, then acetonitrile/water=2/1), then crystallized from mixed solvent of ethyl acetate/hexane (1/1) to obtain 5-dimethoxymethyl-2-(2-morpholinoethoxy)benzoic acid (0.58 g, 21%).
