HCID 597711634-Cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylic acid [2-cyclohex-1-enyl-4-(2-oxo-hexahydro-pyrimidin-5-yl)-phenyl]-amide

Procedure

5-(4-Amino-3-cyclohex-1-enyl-phenyl)-tetrahydro-pyrimidin-2-one (22 mg, as prepared in the previous step) was coupled to 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylic acid, potassium salt (as prepared in Example 1, step (d), 27.2 mg, 0.0890 mmol) as described in Example 1, step (1) to obtain the title compound (14 mg, over two steps) after purification on silica (3% MeOH-EtOAc): Mass spectrum (ESI, m/z): Calcd. for C27H36N6O3Si, 521.2 (M+H). found 521.1.
