Reaction Steps

A mixture of (±)-2-amino-4-(3-chlorophenyl)-α-(4-chlorophenyl)-α-(1-methyl-1H-imidazol-5-yl)-6-quinolinemethanol (0.000210 mol) (see Example B8) and isocyanato-benzene (0.000630 mol; 3 equiv) in THF (1 ml) was stirred for 5 hours at 60° C. Water (a few drops) was added. The solvent was evaporated. The residue was HPLC purified. The product fractions were collected and the solvent was evaporated, yielding 0.071 g (56.77%) of (±)-N-[4-(3-chlorophenyl)-6-[(4-chlorophenyl)hydroxy(1-methyl-1H-imidazol-5-yl)methyl]-2-quinolinyl]-N′-phenylurea, MS (ESI) m/z: 594 596 598.
