Procedure

A solution of the ethyl (RS)-(3-amino-5-methyl-phenyl)-(4-cyano-phenylamino)-acetate (475 mg, 1.54 mmol) obtained in Example 216.3, 2-chloropyrimidine (400 mg, 3.38 mmol), diisopropylethylamine (317 μl, 1.85 mmol) and 1,8-diazabicyclo[5.4.0]undec-7-ene (276 μl, 1.85 mmol) in THF (4 ml) was heated under reflux for 2 h. The reaction mixture was concentrated and the residue was purified by chromatography (SiO2, hexane/EtOAc 1:1→EtOAc). There were obtained 193 mg (23%) of ethyl (RS)-(4-cyano-phenylamino)-(3-methyl-5-{1-[3-(pyrimidin-2-ylamino)-propyl]-azepan-2-ylideneamino}-phenyl)-acetate as yellowish foam; MS: 540 ([M+H]+).
