To a solution of 6-phenethyl-7-(trifluoromethyl)-1,2,3,4-tetrahydro-[1,4]diazepino[6,7,1-hi]indole (prepared as described in Example 2 above, 53 mg, 0.14 mmol) in CH2Cl2 at 0° C. was added 2-acetoxyacetyl chloride (19 mg, 0.14 mmol) and diisopropylethylamine (0.072 mL, 0.42 mmol) and the resulting mixture stirred at 0° C. Upon completion of the reaction completion, the solvent was evaporated and the resulting residue triturated with methanol-diethyl ether to yield 2-oxo-2-(6-phenethyl-7-(trifluoromethyl)-3,4-dihydro-[1,4]diazepino[6,7,1-hi]indol-2(1H)-yl)ethyl acetate (20 mg) as a white solid.
