Sodium Chloride → HCID 22710468, compound

Participants

Reaction Steps

To a solution of 1-(tert-butoxycarbonyl)-3,3-dimethylpiperazine (125 mg) in methylene chloride (3.0 ml) were added triethylamine (90 ml) and 6-chloronaphthalene-2-sulfonyl chloride (167 mg). The resulting mixture was stirred at room temperature for 84 hours. The reaction mixture was diluted with methylene chloride and added with a saturated aqueous solution of sodium chloride to form two layers. The organic layer obtained by separation was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The crudely purified product was purified by chromatography on a silica gel column (hexane:ethyl acetate=8:1), whereby the title compound (155 mg) was obtained as a colorless solid.
