实验过程

To a solution of 2,4,5,6-tetrachloro-pyrimidine (2.0 g, 9.2 mmol) in THF (20 mL) and triethylamine (excess) was added 3-oxa-8-aza-bicyclo[3.2.1]octane (2.7 g, 18 mmol) at −78° C. The reaction slowly warmed to room temperature and a white precipitate formed. To the reaction was added water (2.0 mL) and the mixture was refluxed for three days. The reaction was cooled and water was added to precipitate a white solid. The solids were collected by filtration and washed with diethyl ether to yield the title compound (2.0 g). MS m/z=372 (M+H).
