30459-17-7, 1-(4-Trifluoromethylphenyl)piperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

In a 20-mL screw-cap vial, 100 mg (0.3 mmol) 2-(2-chlorophenyl)-1-(4-chlorophenyl)- 1H imidazole-4-carboxylic acid, 87 mg (0.33 mmol) TFFH, and 5.0 equiv. PS-DIEA (loading level: 3.50 mmol/g, 429 mg, 1.5 mmol) were heated in 8 mL 1,2-dichloroethane at 35C overnight. The formation of acyl fluoride was monitored by LC-MS. To the mixture, 1.1 equiv. (76 mg, 0.33 mmol) 1-(4-trifluormethylphenyl)-piperazine was added and the reaction continued overnight. The mixture was filtered through a filter tube (polypropylene frit), and the filtrate was evaporated under reduced pressure. The crude product was redissolved in 1 mL MeOH and purified by preparative HPLC to give 45.9 mg of 1-{ [2-(2-chlorophenyl)-1-(4-chlorophenyl)-1H-imidazol-4- yl]carbonyl}-4-[4-(trifluoromethyl)phenyl]piperazine as the trifluoroacetate salt (yellow oil, 23% yield). ?H NMR (400 MHz, CD3COCD3) No. 7.95 (s, 1 H), 7.60 (m, 1 H), 7.30-7.50 (m, 7 H), 7.25 (d, 2 H), 7.05 (d, 2 H), 4.5 (bs, 2 H), 3.80 (bs, 2 H), 3.35 (m, 4 H) ; LC-MS m/z 545.3 (MH+), retention time 4.21 min (method 2), 30459-17-7
