Procedimiento

1 g 2,4-dichloro-5-methoxy-pyrimidine are dissolved in 4 mL butanol and combined with 1.04 g 4,5,6,7-tetrahydroimidazopyridine dihydrochloride and 2.96 mL ethyldiisopropylamine. This mixture is stirred for 16 h at 50° C. and then the solvent is eliminated in vacuo. The crude mixture is purified by column chromatography. The carrier material used is C18-RP-silica gel and a gradient is run through which consists at the starting point of 95% water and 5% acetonitrile and at the finishing point of 70% water and 30% acetonitrile. 0.2% formic acid is added to both eluants. The suitable fractions are freeze-dried.
