Versuchsvorschrift

4-[2-(4-Aminopiperidin-1-yl)ethyl]-6-chloro-1,2,4-benzotriazin-3(4H)-one (Intermediate 207, 67 mg) was reacted with 3-oxo-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine-6-carbaldehyde (WO 2004/058144) (360 mg) and sodium acetoxyborohydride (76 mg) as described for Example 107. Chromatography on silica gel with 0-20% methanol in dichloromethane and trituration from ether gave 33 mg of the title compound.
