Procedure

Starting from 5-(3-ethoxy-4-iodo-5-methoxymethoxy-benzyl)-pyrimidine-2,4-diamine (2.11 g; 4,9 mmol) and N-(5-bromo-2-methyl-phenyl)-2,2,2-trifluoro-acetamide (prepared from 5-bromo-2-methyl-aniline analogously to example 41) (2.3 g; 8.17 mmol), 0.963 g (30%) 3′-amino-4-(2,4-diamino-pyrimidin-5-ylmethyl)-6-ethoxy-4′-methyl-biphenyl-2-ol is obtained as a beige powder after Suzuki coupling (in situ generation of R2—B(OH)2) and splitting off of the protective group under acid conditions.
