Reaction Steps
A suspension of 1-tosyl-4-(2,2,2-trifluoroethyl)piperazine (700 mg, 2.2 mmol) in a 30% HBr/acetic acid solution was stirred at 90° C. for 90 minutes. Toluene was added to the suspension. An orange solid was filtered off and washed with diethyl ether to afford the desired compound (400 mg, 55% yield) as a bis HBr salt.
