2-(Trifluoromethyl)benzoyl chloride → HCID 44203151, compound

Participants

Reaction Steps

To a stirred solution of 1-Boc-piperazine (1.96 g, 10.5 mmol) in dichloromethane (50 mL) was added 2-trifluoromethylbenzoyl chloride (2.08 g, 10.0 mmol) dissolved in dichloromethane in the presence of triethylamine (3 mL) at 0° C. The resulting mixture was stirred at room temperature for 18 hours and then quenched with water (25 mL). The organic phase was washed with water, brine, then dried over MgSO4 and concentrated in vacuo to afford 4-(2-trifluoromethylbenzoyl)piperazine-1-carboxylic acid tert-butyl ester as a pale yellow solid.
