Reaction Steps

A solution of N-trifluoroacetyl-7-allyloxy-8-bromo-1-isopropyl-2,3,4,5-tetrahydro-1H-3-benzazepine (0.011 g, 0.026 mmol) in methanol (0.5 mL) was treated with of 15% aqueous NaOH (0.5 mL), and stirred for 3 hours at 50° C. The product mixture was diluted with brine (5 mL), extracted twice with EtOAc (5 mL), dried with MgSO4, and concentrated to give 0.010 g of a clear oil. 1H NMR (400 MHz, CD3OD) 7.09 (s, 1H), 6.62 (s, 1H), 5.94 (m, 1H), 5.32 (dd, 1H), 5.12 (dd, 1H), 4.46 (d, 2H), 3.19 (m, 1H), 3.05 (m, 2H), 2.66 (m, 1H), 2.5 (bm, 2H), 2.3-2.1 (m, 2H), 0.95 (d, 3H), 0.63 (d, 3H). MS calculated for C16H22BrNO+H: 324, observed: 324.
