참여 물질

반응 단계

To a solution of methyl 2-chloro-5-nitroisonicotinate (Intermediate 26A) (0.1 g, 0.46 mmol) in methanol (3 mL) under nitrogen was added 1,4-diazabicyclo[3.2.2]nonane (0.18 g, 0.55 mmol) and triethylamine (7 mg, 0.69 mmol), reaction then stirred overnight. The reaction mixture was concentrated and purified by a 10 g silica column eluting with 40% ethylacetate in hexane to afford methyl 2-(1,4-diazabicyclo[3.2.2]nonan-4-yl)-5-nitroisonicotinate.
