Reaction Steps

To a solution of 8-methoxy-4,5-dihydro-1H-benzo[b]azepin-2(3H)-one (2 g) in THF (100 mL), lithium aluminum hydride (0.79 g) was added, and the reaction heated to reflux. After stirring for 1 hour, the heat was removed. Water (6 mL) was added followed by NaOH (10%, 15 mL), the flocculated solids removed by filtration, and the eluent concentrated to provide the title compound (1.9 g) as a pale brown oil: 1H NMR (DMSO-d6) δ 6.88 (d, 1H); 6.37 (d, 1H), 6.22 (dd, 1H), 5.14 (s, 1H), 3.62 (s, 3H), 2.90-2.85 (m, 2H), 2.57-2.53 (m, 2H), 1.67-1.59 (m, 2H), 1.52-1.45 (m, 2H).
