Triethylamine → HCID 19364510, compound

Participants

Reaction Steps

141 mg of the alcohol compound thus obtained was dissolved in 2 ml of ethyl acetate, and 62 μl of methanesulfonyl chloride and 161 μl of triethylamine were added thereto, followed by stirring at room temperature for 30 minutes. Insoluble precipitates were filtered off from the reaction solution. Then, the filtrate was concentrated under reduced pressure, and the residue was dissolved in 5 ml of dimethylformamide. Then, 255 mg of sodium azide was added thereto, followed by heating at 80° C. for 4 hours. The reaction solution was left to cool to room temperature. Then, ethyl ether and water were added thereto for extraction. The organic layer was washed with a saturated sodium chloride aqueous solution and then dried over anhydrous magnesium sulfate. The drying agent was filtered off, and then, the solvent was distilled off under reduced pressure. The residue was heated and refluxed together with 187 mg of triphenylphosphine in 7 ml of 10%-water containing tetrahydrofuran for one hour. The reaction solution was evaporated to dryness under reduced pressure. Then, the residue was dissolved in ethanol and again evaporated to dryness under reduced pressure. The obtained residue was purified by silica gel column chromatography (chloroform/methanol=50/1→10/1) to obtain 129 mg (yield: 92%) of (1RS,2SR)-2-(4-chlorophenyl)-1-methyl-3-(4-phenylethynylphenyl)propylamine
