Reaction Steps

A solution of N-trifluoroacetyl-7-(2-Methyl-2H-pyrazol-3-yl)-1-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine (48 mg, 0.14 mmol) in methanol (2 mL) was treated with 15% aqueous NaOH (2 mL), and the solution stirred overnight at 20 C. The product mixture was concentrated, extracted 3 times with CH2Cl2 (5 mL), dried with Na2SO4 and the solvent evaporated. Flash chromatography (0-15% MeOH in CH2Cl2, silica) resulted in 30 mg of a clear oil. 1H NMR (400 MHz, CDCl3) d 7.48 (s, 1 H), 7.21 (m, 2 H), 7.13 (s, 1 H), 6.27 (s, 1 H), 3.89 (s, 3 H), 3.3-2.9 (m, 9 H), 2.79 (dd, J=7, 14 Hz, 1 H), 1.40 (d, J=8 Hz, 3 H). MS calculated for C15H19N3+H: 242, observed: 242.
