Procedure

To a stirring solution of 4-[2-(3-Aminomethyl-oxetan-3-ylmethoxy)-3,4-dimethoxy-phenyl]-indan-1-one (150 mg, 0.391 mmol) in dichloromethane (15 mL), methoxy-acetic acid (142 mg, 1.56 mmol), 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC.HCl) (112 mg, 0.587 mmol) and 1-Hydroxy-7-azabenzotriazole (HOAt) (106 mg, 0.78 mmol) and triethylamine were 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 layer was washed with brine and dried over anhydrous sodium sulphate and concentrated under reduced pressure. Purification by column chromatography (silica gel, 0-3% methanol in dichloromethane) afforded the title compound as a solid.
