Participants

Reaction Steps

To a 100-mL, round-bottomed flask containing 4-chloro-6-(4-trifluoromethyl-phenyl)-pyrimidine, (Example 2(a), Method A), (0.20 g, 0.77 mmol) and 6-hydroxyindole (0.21 g, 1.5 mmol, Aldrich) in 1,4-dioxane (10 mL), was added NaOH (8.0 mL, 8.0 mmol, 1.0 N). The mixture was heated at reflux for 8 h, and after cooling to room temperature, the reaction mixture was concentrated in vacuum. EtOAc (30 mL) was added, and the organic layer was washed with brine (10 mL), water (15 mL), dried over Na2SO4, filtered, and concentrated in vacuum. After the product was purified by silica gel chromatography (5:1 hexanes/EtOAc), the residue was dissolved in acetone (3 mL). Water (4 mL) was then added dropwise to afford a white precipitate, which was collected by filtration, washed with water (0.5 mL), and dried under vacuum at 50° C. for 48 h to furnish the title compound. Mp: 206–209° C. MS (ESI, pos. ion) m/z: 356 (M+1); Anal. Calcd for C19H12F3N3O.(H2O)0.2: C, 63.58; H, 3.48; N, 11.71. Found: C, 63.82; H, 3.37; N, 11.61
