Participants

Reaction Steps

To a stirred suspension of 1 (2 tert-butylphenyl)piperazine dihydrochloride (29 mg, 0.1 mmol) and triethylamine (0.021 mL, 0.3 mmol) in THF (1.0 mL) was added acetyl chloride (23 mg, 0.3 mmol) at rt. After stirring for 2 h at room temperature, saturated sodium hydrogen carbonate solution (1.5 mL) was added to the mixture, and the mixture was extracted with ethyl acetate (2 mL). The organic layer was separated by phase separation filter kit and the filtrate was evaporated under reduced pressure. The resulting residue was dissolved in DMSO (1 mL) and the solution was purified by preparative HPLC. The eluted fraction was evaporated by air blowing at 60° C. to give a title compound (20.5 mg, 79%). LC/MS (ESI+) m/z 261 [M+H], purity 100%.
