Procedure
To a stirring solution of 4-(2-((3-(azidomethyl)oxetan-3-yl)methoxy)-3,4-dimethoxyphenyl)-indan-1-one (3 g, 7.57 mmol) in in tetrahydrofuran (30 mL), were added triphenylphosphine (7.6 g, 29.28 mmol) and the reaction mixture was stirred at RT for 2 h. Water (3 mL) was added to the above reaction mixture and the resultant reaction mixture was heated to 80° C. for 1 h. The reaction mixture was concentrated under reduced pressure and the obtained residue was acidified with 1N hydrochloric acid solution. Then extracted with ethyl acetate (3×) and the aq layer was basified with sodium bicarbonate solution and extracted with ethyl acetate and the combined ethyl acetate layer was washed with brine, dried over anhydrous sodium sulphate and concentrated under reduced pressure to afford the title compound as a liquid.
