실험 절차
To a solution of 2 g of methyl 3-cyclopropyl-3-oxopropanoate in 20 ml of dichloromethane was added dropwise 1.24 ml of sulfuryl chloride under ice-cooling, followed by stirring at room temperature for 5 hours. To the reaction mixture was added water under ice-cooling, and chloroform was further added thereto to carry out a layer separation operation. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure to obtain 2.48 g of methyl 2-chloro-3-cyclopropyl-3-oxopropanoate.
