Versuchsvorschrift

To a stirred solution of 6-chloro-2,3,4,9,10,10a-hexahydro-1H-3a,8,9-triaza-cyclopenta[b]fluorene (700 mg, 2.82 mmol) in DMF (10 mL) were added portionwise NaH (60%, 338 mg 8.46 mmol) and 4-oxiranyl-pyridine (511 mg, 3.38 mmol). The reaction mass was stirred at RT for 16 h. The progress of reaction was monitored by LCMS. The reaction mass was quenched with ice cold water (200 mL) and extracted with EtOAc (3×150 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 under reduced pressure. The residue obtained was purified by silica gel column chromatography (0-15% DCM/MeOH) followed by reverse phase HPLC to yield the title compound;
