Reaktionsschritte
2.27 g (10 mmol) of 2,4-dichloro-3-bromopyridine, 2.6 g (15 mmol) of cis-4-phenylcyclohexylamine and 0.1 g of ammonium chloride are heated at 120° C. for 10 hours in 10 ml of N-methylpyrrolidone. After cooling, saturated sodium hydrogencarbonate solution is added and the reaction product is extracted with ethyl acetate. Purification is carried out by column chromatography. Yield: 1.9 g (52%); m.p. 105° C.
