Procedure

To a stirred solution of 2,3,4,5,6,10c-hexahydro-1H-3a,6,7-triaza-cyclopenta[c]fluorene (1 g, 4.6 mmol) in DMF (20 mL) were portion wise added NaH (60%, 0.552 g, 13.8 mmol) and 4-(oxiran-2-yl)pyridine (0.709 g, 5.6 mmol). The reaction mass was stirred at RT overnight. The progress of reaction was monitored by LCMS. The reaction mixture was quenched with ice cold water (300 mL) and extracted with EtOAc (3×100 mL). The combined organic layer was washed with water (10×100 mL), followed by brine (2×100 mL), dried over anhydrous sodium sulfate and concentrated. The residue was purified by silica gel column chromatography followed by reverse phase HPLC to yield the title compound;
