Procedure

To a stirring solution of 4-[2-(3-Aminomethyl-oxetan-3-ylmethoxy)-3,4-dimethoxy-phenyl]-indan-1-one (Compound 191) (150 mg, 0.391 mmol) in dichloromethane (15 mL), were added triethylamine (118 mg, 1.174 mmol) and acetyl chloride (61 mg, 0.777 mmol) 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, dried over anhydrous sodium sulphate and concentrated under reduced pressure. Purification by column chromatography (silica gel, 0-2% methanol in dichloromethane) afforded the title compound as a solid.
