1-(溴甲基)环丙烷羧酸甲酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Triphenylphosphine (10 g) and carbon tetrabromide (16 g) were added to a solution of the compound (4.20 g) obtained in Referential Example 162 in methylene chloride (168 ml) at room temperature under a nitrogen atmosphere. After 2 minutes, a saturated aqueous solution of sodium hydrogencarbonate was added thereto. After the resultant organic layer was washed with saturated aqueous solution of sodium chloride and dried over anhydrous sodium sulfate, the solvent was distilled off under reduced pressure. The resultant residue was purified by column chromatography on silica gel (ethyl acetate:hexane=1:19) to obtain the title compound (2.15 g). After the resultant organic layer was washed with saturated aqueous solution of sodium chloride dried over anhydrous sodium sulfate the solvent was distilled off under reduced pressure The resultant residue was purified by column chromatography on silica gel (ethyl acetate:hexane=1:19)

实验步骤: To a solution of the compound obtained in Referential Example 162 (4.20 g) in methylene chloride (168 mL) were added triphenylphosphine (10 g) and carbon tetrabromide (16 g) at room temperature under nitrogen atmosphere, and after 2 minutes, saturated aqueous sodium hydrogencarbonate was added thereto. The organic layer was washed with saturated brine, and was dried over sodium sulfate anhydrate. The solvent was distilled away under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate hexane=1:19), to thereby give the title compound (2.15 g). The organic layer was washed with saturated brine was dried over sodium sulfate anhydrate The solvent was distilled away under reduced pressure the residue was purified by silica gel column chromatography (ethyl acetate hexane=1:19)
