Procedure

To a stirring solution of 4-(2-((3-(hydroxymethyl)oxetan-3-yl)methoxy)-3,4-dimethoxyphenyl)-indan-1-one (4 g, 10.41 mmol) in dichloromethane (70 mL) at 0° C., were added triethylamine (3.15 g, 31.25 mmol) and mesyl chloride (1.78 g, 15.614 mmol), the resultant reaction mixture was warmed to RT and stirred for 30 min. 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 to afford (3-((2,3-dimethoxy-6-(1-oxo-2,3-dihydro-1H-inden-4-yl)phenoxy)methyl)oxetan-3-yl)methyl methanesulfonate as a solid.
