Reaction Steps

5,5-Dimethyl-8-nitro-2,3,4,5-tetrahydro-1H-benzo[b]azepine (0.519 g, 2.36 mmol), Pyridine (0.420 mL, 5.19 mmol), 4-Dimethylaminopyridine (21 mg, 0.17 mmol) and anhydrous 1,2-Dichloroethane (8.5 mL) were combined in a round bottom flask. α-Phthalimidoacetyl Chloride (1.105 g, 4.942 mmol) was added to the mixture and it was stirred at room temperature for 16.5 hours. The reaction was concentrated under reduced pressure and purified by normal phase chromatography to yield a yellow solid, 2-[2-(5,5-Dimethyl-8-nitro-2,3,4,5-tetrahydro-benzo[b]azepin-1-yl)-2-oxo-ethyl]-isoindole-1,3-dione (55%) LCMS: m/z=408.11 (M+H+); 1H NMR (400 MHz, CDCl3) δ 8.21 (m, 2H), 7.87 (m, 2H), 7.74 (m, 3H), 4.74 (m, 1H), 4.55 (d, 1H, J=16.9), 4.55 (d, 1H, J=16.7), 2.68 (m, 1H), 2.23 (m, 1H), 1.83 (m, 1H), 1.68 (m, 1H), 1.51 (m, 6H), 1.26 (m, 1H).
