Procedure

To a cooled (0° C.) mixture of (quinolin-6-ylthio)acetaldehyde (40.6 mg, 0.2 mmol) and D-proline (4.6 mg, 0.04 mmol) in chloroform (1.0 mL) was added N-chlorosuccinimide (26.7 mg, 0.2 mmol) with stirring. The mixture was stirred at 0° C. for 30 min, then gradually warmed to ambient temperature for 2 h. To the mixture was added methyl 4-(3-amino-1,2,4-triazin-6-yl)-2-fluorobenzoate (24.8 mg, 0.1 mmol). The reaction mixture was stirred for 1 h. The solvent was removed under reduced pressure. The residue was dissolved in isopropanol (2 mL) and heated to 100° C. overnight. After cooling, the mixture was filtered and the filtrate was purified by RP-HPLC (pH 10) to afford the desired product. LCMS: (M+H)=432.3.
