Procedure

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, and 2-isocyanato-propane (3 equiv, 0.00063 mol) in THF (1 ml) was heated at 60° C. for 5 hours. A few drops of water were added. The mixture was evaporated till dryness and purified by HPLC. The product fractions were collected and the solvent was evaporated, yielding 0.024 g (20.3%) of N-[4-(3-chlorophenyl)-6-[(4-chlorophenyl)hydroxy(1-methyl-1H-imidazol-5-yl)methyl]-2-quinazolinyl]-N′-(1-methylethyl)-urea, MS (ESI) m/z: 561 563 565.
