Reaction Steps

To a solution of 5-aminoindane (2.0 g, 15.0 mmol) in 5 mL of anhydrous pyridine at 0° C. was added acetic anhydride (2.1 mL, 22.5 mmol) and the solution was stirred at rt for 3 h. The solution was then added to 50 mL of water and the resulting solid filtered and washed with water, then dried under vacuum to yield the title compound (2.23 g, 78%). 1H NMR (CDCl3): 7.44 (s, 1H), 7.2 (bs, 1H), 7.12 (s, 2H), 2.88 (q, 4H), 2.18 (s, 3H), 2.09 (p, 2H).
