실험 절차
A solution of thiourea (1.1 g) in ethanol (10 mL) was brought to reflux. Ethyl 2-bromo-4-methyl-3-oxopentanoate (3.0 g) was then added and the reaction mixture refluxed further for 1 h. The reaction was complete (by TLC) and was concentrated in vacuum. Flash chromatography (100% DCM→90:10 DCM:MeOH) afforded the product (1.1 g).
