Cyclohexanecarboxylic acid → N-[4-(3-chlorophenyl)-6-[(4-chlorophenyl)hydroxy(1-methyl-1H-imidazol-5-yl)methyl]-2-quinazolinyl]-cyclohexanecarboxamide

Participants

Reaction Steps

A mixture of 2-amino-4-(3-chlorophenyl)-α-(4-chlorophenyl)-α-(1-methyl-1H-imidazol-5-yl)-6-quinazolinemethanol (0.00021 mol), obtained in Example B19, cyclohexanecarboxylic acid (1.2 equiv, 0.000252 mol), N′-(ethylcarbonimidoyl)-N,N-dimethyl-1,3-propanediamine, monohydrochloride (1.5 equiv, 0.000315 mol), 1-hydroxy-1H-benzotriazole (1.5 equiv, 0.000315 mol) and triethylamine (1.5 equiv, 0.000315 mol) in THF (2 ml) was stirred at room temperature for 18 hours, then taken up in water. The organic layer was separated and the solvent was evaporated. The residue was purified by HPLC. The product fractions were collected and the solvent was evaporated, yielding 0.006 g (4.8%) of N-[4-(3-chlorophenyl)-6-[(4-chlorophenyl)hydroxy(1-methyl-1H-imidazol-5-yl)methyl]-2-quinazolinyl]-cyclohexanecarboxamide, MS (ESI) m/z: 586 588 590.
