Reaktionsschritte

12.4 g (62.0 mmol) of 4-chloro-6-ethyl-5-methoxycarbonylpyrimidine, 11.1 g (62.0 mmol) of cis-4-trimethylsilylcyclohexylamine and 12.55 g (124 mmol) of triethylamine were heated in 30 ml of toluene at 90° C. for 3 hours. After complete reaction, the mixture was partitioned between dichloromethane and water to give, after further extraction with dichloromethane and column chromatography on silica gel, 17.76 g (85.4% of theory) of the cyclohexylaminopyrimidine as a pale brown oil, nD21 =1.5230.
