Versuchsvorschrift

168 mg 2-(5-Azetidine-3-yl-[1,2,4]triazole-3-yl)-6-methylpyridine×2HCl (intermediate example 44.1; 60% pure) are dissolved in 2.8 ml NMP. After addition of 0.1 ml triethylamine the reaction mixture is stirred for one hour. 100 mg (0.32 mmol) 4-(3-Methyl-6-phenylimidazo[1,2-a]pyrimidin-7-yl)benzaldehyde (intermediate example 12.0) and 0.03 mL acetic acid are added and the reaction mixture is stirred overnight at room temperature. 74.4 mg (0.35 mmol) NaBH(OAc)3, are added in portions and the reaction mixture is stirred at room temperature for 20 hours. The reaction mixture is treated with saturated NaHCO3 and the precipitate filtered off, washed with water and dried. After chromatography of the precipitate on silica gel (dichloromethane/methanol) 36.6 mg (21%) of the desired product are obtained.
