Participants

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) d 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.
