Participants

Reaction Steps

Synthesized from compound 26. To a solution of compound 26 (0.2 g, 0.6 mmol) in 5 mL of CH2Cl2 was added 1 mmol of TEA and 0.8 mmol of 2-trifluoromethyl-benzoyl chloride. The reaction was stirred overnight at room temperature. After the solvents were evaporated, the residue was purified with semi-preparative HPLC to afford a solid (15% yield). MP: 140-142° C.; MS (ES−): 469; 1H NMR (400 MHz, CDCl3): 1.92-2.10 (m, 2H), 2.91-3.10 (m, 4H), 3.36-3.44 (m, 2H), 3.64-3.74 (m, 2H), 3.93 (m, 2H), 7.38 (m, 1H), 7.57 (m, 3H), 7.79 (m, 2H), 7.93 (m, 1H). Anal. Calcd. for C23H21F3N6O2.0.9HCl: C, 54.89; H, 4.39; N, 16.70; Found: C, 54.93; H, 4.43; N, 16.34.
