실험 절차

A solution of N-trifluoroacetyl-8-bromo-1-isopropyl-7-methoxy-2,3,4,5-tetrahydro-1H-3-benzazepine (0.013 g, 0.03 mmol) methanol (0.5 mL) was treated with 15% aqueous NaOH (0.5 mL), and stirred overnight at 20 C. The product mixture was diluted with brine (5 mL), extracted twice with EtOAc (5 mL), dried with MgSO4, and concentrated to give 0.10 g of a clear oil. 1H NMR (400 MHz, CD3OD) d 7.08 (s, 1 H), 6.64 (s, 1 H), 3.72 (s, 3 H), 3.2-3.10 (m, 3 H), 2.7-2.5 (m, 3 H), 2.3-2.1 (m, 2 H), 0.96 (d, 3 H), 0.63 (d, 3 H). MS calculated for C14H20BrNO+H: 298, observed: 298.
