Procedimiento

A mixture of 4-(5-nitro-pyrimidin-2-yl)-1,4-diaza-bicyclo[3.2.2]nonane (0.86 g, 2.9 mmol), palladium (0.25 g, 10% on activated carbon) and ethanol (50 ml) was stirred under hydrogen for 10 min (200 ml of hydrogen consumed). The rection-mixture of 2-(1,4-diaza-bicyclo[3.2.2]non-4-yl)-pyrimidin-5-ylamine was filtered through celite and was washed with ethanol (50 ml). The ethanolic solution of 2-(1,4-diaza-bicyclo[3.2.2]non-4-yl)-pyrimidin-5-ylamine was mixed with benzoylchloride 0.41 g, 2.90 mmol) and was stirred for 15 h at room-temperature. The title product precipitated as hydrochloric acid salt by addition of hydrochloric acid in ethanol. Yield 0.38 g (36%). LC-ESI-HRMS of [M+H]+ shows 324.1817 Da. Calc. 324.182435 Da, dev. −2.3 ppm.
