Procedure

To 6-phenethyl-7-(trifluoromethyl)-1,2,3,4-tetrahydro-[1,4]diazepino[6,7,1-hi]indole (prepared as described in Example 2 above, 37 mg, 0.1 mmol) and N,N-dimethylglycine hydrochloride (14 mg, 0.1 mmol) in THF (7 mL) was added triethylamine (50 mg, 0.5 mmol), and 2-(7-aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU; 43 mg, 0.1 mmol). The resulting mixture was stirred overnight, then partitioned between ethyl acetate and water. The organic phase was washed sequentially with NaHCO3 and brine, then dried and concentrated. The residue was purified by reverse-phase chromatography (acetonitrile/water/trifluoroacetic add) to yield 2-(dimethylamino)-1-(6-phenethyl-7-(trifluoromethyl)-3,4-dihydro-[1,4]diazepino[6,7,1-hi]indol-2(1H)-yl)ethanone.
