C, but preferably at the boiling point of the particular solvent which is used. The presence of an acid-binding agent, such as an alkali metal alcoholate, an alkali metal hydroxide, an alkali metal carbonate, especially potassium carbonate, or a tertiary organic base, particularly triethylamine or pyridine, or of a reaction accelerator, such as potassium iodide, is of advantage.Method BBy reacting a compound of the formula ##STR7## wherein A, R.sub.2 and R.sub.3 have the same meanings as in formula I, with a phenylalkylamine of the formula ##STR8## wherein R.sub.4, R.sub.5, R.sub.6 and n have the same meanings as in formula I, andZ has the same meanings as in formula II.The reaction is carried out in an inert solvent, such as acetone, dimethylformamide, dimethylsulfoxide or chlorobenzene, and, depending upon the reactivity of substituent Z, at a temperature between 0 and 150.degree.
