General Procedure for the Preparation of Compounds 4al A mixture of N-isocyaniminotriphenylphosphorane (1 mmol) and the appropriate aldehyde (1 mmol) was dissolved in hot THF (5 mL). Then the appropriate 4 (3H)-quinazolinone (1 mmol) was added to the reaction mixture which was refluxed for 3 h. Then, the solvent was removed under the reduced pressure, and the residue was purified by TLC using CHCl3EtOAc (3:1) as eluent. The solvent was removed, and the product was obtained as colorless crystals. 3-[1-Hydroxy-1-(4-fluorophenyl) methyl]-5-phenyl-[1,2,4]triazolo[4,3-c]quinazoline (4c) Yield 0.34 g (93%); colorless crystals; mp 192193 C.
