실험 절차

A suspension of Fenclorim (4,6-dichloro-2-phenylpyrimidine)(0.1 g, 0.44 mmol), 3-amino-5-methylpyrazole (0.045 g, 0.47 mmol), N,N-diisopropylethylamine (0.08 ml, 0.47 mmol) and sodium iodide (0.067 g, 0.44 mmol) in n-butanol (5 ml) were heated at 117° C. for 18 hours. The solvent was removed in vacuo and the crude product purified by flash chromatography (silica gel, 3:2 Petrol:EtOAc) to afford 0.037 g (29% yield) of (6-Chloro-2-phenyl-pyrimidin-4-yl)-(5-methyl-2H-pyrazol-3-yl)-amine as a off-white solid. A suspension of the above pyrimidine (0.037 g, 0.13 mmol) and thioacetamidothiophenol (0.108 g, 0.64 mmol) in tert-butanol was heated at 85° C. under nitrogen for 2 days. The reaction mixture was cooled to room temperature and the solvent removed in vacuo. The concentrate was dissolved in EtOAc, and washed with NaHCO3 (sat, aq.). The organic layer is concentrated in vacuo, and the crude product by preperative HPLC. The residual disulfide that still remained in the mixture after HPLC may be removed by precipitation from EtOAc and filtration. The mother liquor was concentrated to afford IV-3 (7 mg, 13% yield) as an off-white solid: mp 235–236° C.; 1H NMR (DMSO) δ 2.10 (3H, s), 2.21 (3H, s), 6.33 (1H, br s), 7.50 (3H, m), 7.7–7.59 (2H, m), 7.76–7.78 (2H, m), 8.25 (2H, m), 9.72, 10.26 and 11.93 (3H, 3×br s); IR (solid) 1669, 1585, 1551, 1492, 1392, 1372, 1312, 1289, 1259, 1174, 1102, 1089, 1027, 1015, 984; MS 417.3 (M+H)+.
