Procedure
3.1 g (14.4 mmol) of the chloro compound (Example 3, Step A) and 3.2 g (14.4 mmol) of the amine (Example 1, Step C) were heated in 75 ml ethanol according to Example 4, Step C. The title compound was obtained as an oil after chromatography (silica gel; dichloromethane with ascending polarity by addition of up to 3% ethanol).
