反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 1-tert-Butyl-4-(4-phenylbutanoyl)piperazine (A, 2.64 g) was dissolved in trifluoroacetic acid (10 mL)—dichloromethane (10 mL). After siring for 1 hr, the reaction mixture was evaporated in vacuo. Toluene and methanol were added to the residue, then evaporated in vacuo to give the titled compound (1.63 g) as a colorless solid. the reaction mixture was evaporated in vacuo Toluene and methanol were added to the residue evaporated in vacuo
