Procedure

TBTU (69 mg, 0.22 mmol) was added to a stirred solution of racemic 14b (60 mg, 0.0.144 mmol), morpholine (19 μL, 0.22 mmol), and N,N-diisopropylethylamine (300 μL, 1.7 mmol) in DMF (3 mL). The mixture was shaken at 22° C. for 18 hr. The resulting solution was injected on a Shimadzu preparative liquid chromatograph. The product containing fraction was concentrated on a Speed Vac® to leave methyl 13-cyclohexyl-6,7-dihydro-6-(morpholinylcarbonyl)-5H-indolo[2,1-a][2]benzazepine-10-carboxylate as a colorless solid (60 mg, 86%). ESI-MS m/z 487 (MH+).
