Reaction Steps

A mixture of 5-methoxyacetamidoindan (5.50 g, 0.027 mol) and glacial acetic acid (25 ml) was cooled in an ice-water bath (˜10° C.). Bromine (1.5 ml, 0.029 mol) was then dropwise added over a 20 min period while the temperature was kept between 10-15° C. The reaction mixture was then stirred for a longer 1 hour and then it was poured into an ice-water bath (100 ml) with the aid of water (70 ml). The precipitate was collected by filtration, washed with plenty of water (150 ml) and dried in vacuo over P2O5 to afford the title compound (6.98 g, 91%), m.p. 84-86° C.; 1H-NMR (250 MHz, CDCl3, TMS) 2.09 (m, 2H, 2-CH2), 2.88 (m, 4H, 1-CH2 and 3-CH2), 3.55 (s, 3H, OCH3), 4.04 (s, 2H, 2-CH2OMe), 7.34, 8.22 (2×s, 2H, 4-H, 7-H), 8.83 (s, 1H, CONH);
