Reaction Steps

To a stirring solution of 4-(3,4-Dimethoxy-2-methoxymethoxy-phenyl)-indan-1-one (1.6 g, 4.87 mmol) in methanol (15 mL) at 0° C., was added concentrated hydrochloride acid (3 mL) and the resultant reaction mixture was stirred at 50° C. for 15 min. The reaction mixture was concentrated under reduced pressure and basified with aq sodium bicarbonate solution extracted with ethyl acetate (3×). The combined ethyl acetate layer was washed with brine, dried over anhydrous sodium sulphate and concentrated under reduced pressure. The residue was purified by washing with ether to afford the title compound as a solid.
