실험 절차

A mixture of methyl 5-bromo-4-oxopentanoate (2.51 g, 12.0 mmol), 1-(5-bromo-3-phenoxypyridin-2-yl)thiourea (3.00 g, 9.25 mmol), triethylamine (2.19 mL, 15.7 mmol), and ethanol (60 mL) was refluxed for 3 hours and then stirred at ambient temperature overnight. The solvent was removed to about one third original volume and partitioned between CH2Cl2 and water. The organics were concentrated and purified on silica gel eluting with 40% EtOAc/Hexanes to give the title compound (3.22 g, 80.1% yield).
