Reaction Steps

A product obtained in Example 3 (0.183 g, 0.33 mmol) was add CH3OH (15 ml) and Raney-Ni. The mixture was hydrogenated at room temperature for 1 hours. The mixture was filtered, and the filtrate was concentrated to give the product as yellow-green solide (0.16 g). The solide was recrystallized with ethyl acetate/petroleum ether to give pale yellow powder (0.041 g, 26.7%). mp 162˜164° C. 1HNMR (CDCl3) δ: 2.57˜2.71 (3H, m, CH2), 3.08˜3.12 (2H, m, CH2), 3.36˜3.58 (3H, m, CH2 and N—CH), 3.79 (3H, s, Ar—OCH3), 3.87 (3H, s, Ar—OCH3), 4.02 (1H, br, CH2), 5.55 (1H, s, Ar—OH), 6.59 (1H, s, ArH), 6.89 (1H, s, ArH), 6.95 (1H, s, ArH), 7.51˜7.56 (2H, m, PhH), 7.65˜7.67 (1H, m, PhH), 8.22˜8.24 (2H, m, PhH). MS (EI) m/z: 464 (M−1), 360, 344, 178, 105 (base), 77.
