Versuchsvorschrift

Under N2, a well stirred mixture of 3-pyrimidin-2-yl-8-azabicyclo[3.2.1]octan-3-ol hydrochloride (4.5 g, 14 mmol), 1,1′-(bromomethylene)bis(2-chlorobenzene) (5.0 g, 16 mmol) and K2CO3 (10.0 g, 72 mmol) in CH3CN (50 ml) was stirred under reflux and the reaction was followed by HPLC. After complete reaction (36 to 48 h) the mixture was cooled to 20-25° C., water (50 ml) was added and the suspension was stirred for 3 h. The product was filtered off, washed with water (2×25 ml) and dried to constant weight under vacuum and a slight stream of N2 at 50° C. Yield: 5.5 g (87% abs.). Assay (HPLC): 97% pure vs. standard.
