Procedure

Methyl (E)-3-(1-cyclohexyl-4-oxo-4,5-dihydroimidazo-[1,5-a]quinoxalin-8-yl)acrylate as synthesized in Example 154, 2.0 g was dissolved in 100 mL of acetic acid, and to the solution 10% Pd/C 200 mg was added in nitrogen atmosphere. After substituting the atmosphere with hydrogen, the reaction liquid was stirred at 25° C. for 2 days. The reaction liquid was filtered through Celite and from the filtrate the solvent was distilled off to provide 1.48 g of the title compound.
