Benzoyl chloride → HCID 46673126, compound

Participants

Reaction Steps

1-(Ethoxycarbonylmethyl)piperazine (5.1 g) was dissolved in tetrahydrofuran (300 ml) under a nitrogen atmosphere, and triethylamine (8.25 ml) and benzoyl chloride (3.44 ml) were added thereto while stirring in an ice water bath. The reaction mixture was allowed to warm up to room temperature and stirred for 4 hr. The reaction mixture was partitioned between ethyl acetate (200 ml) and a saturated aqueous solution of sodium hydrogencarbonate (100 ml). The separated organic layer was washed with a saturated aqueous solution of sodium hydrogencarbonate (100 ml), water (100 ml) and brine (100 ml), and dried over sodium sulfate. The solvent was removed under reduced pressure to provide the titled compound as a colorless oil (8.19 g, quantitative).
