Versuchsvorschrift

A solution of 8-aza-bicyclo[3.2.1]octan-3-one hydrochloric acid (5.0 g, 30.9 mmol), 2-chloro-pyrimidine (4.95 g, 43.2 mmol), NaHCO3(7.78 g, 92.7 mmol) and isopropanol (200 ml) was maintained at reflux over weekend. The resulting reaction mixture was concentrated and purified by ISCO to afford 8-pyrimidin-2-yl-8-aza-bicyclo[3.2.1]octan-3-one (4.0 g, 52.9%) as a white solid: MS (M+1)=204. 1H NMR (MeOH) 8.36 (d, J=12 Hz 2H), 6.75 (m, 1H), 4.97 (m, 2H), 2.75 (d, J=12 Hz, 1H), 2.71 (d, J=12 Hz, 1H), 2.32 (d, J=50 Hz, 2H), 2.22 (m, 2H), 1.87 (m, 2H).
