Reaction Steps

To 2-amino-4-(trifluoromethyl)benzamide (840 mg, 4.16 mmol), in THF (15 mL) was added 5-(4-fluorophenyl)-1,3-dioxolane-2,4-dione from Example 16 (1225 mg, 6.24 mmol) and the mixture was heated at 50° C. for 4 h. The solvent was evaporated and the crude 2-(2-(4-fluorophenyl)-2-hydroxyacetamido)-4-(trifluoromethyl)benzamide was dissolved in MeOH (10 mL), added 0.5 M sodium methoxide in MeOH (2.5 mL, 1.25 mmol) and the reaction mixture was heated at 50° C. for 1 h. The solvent was evaporated and then 1N hydrochloric acid was added. The mixture was extracted with EtOAc and the organic phase was dried over sodium sulfate and concentrated in vacuo to afford crude 2-((4-fluorophenyl)(hydroxy)methyl)-7-(trifluoromethyl)quinazolin-4-ol, which was used in next reaction without purification. LC-MS (ESI) m/z 339 (M+Na)+.
