Procedure

To a stirring solution of 3-[2,3-Dimethoxy-6-(1-oxo-indan-4-yl)-phenoxy]-2,2-dimethyl-propionic acid (Compound 199) (30 mg, 0.078 mmol) in dichloromethane, were added 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC.HCl) (22 mg, 0.117 mmol), 1-Hydroxybenzotriazole hydrate (HOBT) (23 mg, 0.156 mmol) and triethylamine (0.1 mL, 0.234 mmolo) and 1M methylamine solution (0.15 mL, 0.156 mmol) and the resultant reaction mixture was stirred at 16 h at RT. The reaction mixture was diluted with water and extracted with dichloromethane (3×). The combined dichloromethane layer was washed with brine and dried over anhydrous sodium sulphate and concentrated under reduced pressure. Purification by column chromatography (silica gel, 0-60% ethyl acetate in pet ether) afforded the title compound as a solid.
