11-chloro-2,3-dihydro-1H-cyclopenta[4,5]pyrido[1,2-a]benzimidazole-4-carboxamide (800 mg) and DIPEA (1.95 ml) were added to an NMP suspension of 3-azabicyclo[4.1.0]hept-6-ylmethanol hydrochloride (1.01 g), and stirring was performed at 220° C. for 60 minutes under microwave irradiation. The reaction liquid was added to water and the precipitate was collected by filtration. The resulting solid was purified by silica gel column chromatography (MeOH/chloroform) to obtain 11-[6-(hydroxymethyl)-3-azabicyclo[4.1.0]hept-3-yl]-2,3-dihydro-1H-cyclopenta[4,5]pyrido[1,2-a]benzimidazole-4-carboxamide (788 mg).
