Participants

Reaction Steps

To a stirring solution of 3-(2,3-dimethoxy-6-(1-oxo-1,3-dihydroisobenzofuran-5-yl)phenoxy)-2,2-dimethylpropanoic acid (100 mg, 0.259 mmol) in dichloromethane (10 mL) was added 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC.HCl) (74.1 mg, 0.388 mmol), triethylamine (1 mL, 0.77 mmol) and 1-hydroxybenzotriazole hydrate (HOBt) (79.2 mg, 0.518 mmol) and stirred for 10 min. To this dimethylamine (23 mg, 0.518 mmol) was added and the resultant reaction mixture was stirred at RT for 16 h. The reaction mixture was diluted with water and extracted with dichloromethane (3×). The combined dichloromethane layers were washed with brine, dried over anhydrous sodium sulphate and concentrated under reduced pressure. Purification of the residue by column chromatography (silica gel, 0-45% ethyl acetate in pet ether) afforded the title compound as a solid (30 mg, 30%).
