Versuchsvorschrift
Intermediate 14 was prepared in analogy to GP 2 by reaction of Intermediate 5 (1.73 g, 7.16 mmol) with commercial 5-bromo-2-chloro-4-methoxypyrimidine (2.00 g, 8.95 mmol, 1.25 eq) to give 1.33 g (43% yield) of the title compound (after crystallization from acetonitrile and column chromatography of the mother liquor residue).
