Procedure
The solution from Example 25C (2 mL) was treated with 4-(1-piperazinyl)phenol (178 mg) in DMSO (1 mL). After 72 hours, the mixture was concentrated under a stream of nitrogen gas and the residue recrystallized from DMSO:methanol (1:1) to provide the title compound. 1H NMR(CDCl3, 300 MHz) 82.81 (4H, t, J=4.8 Hz), 3.18 (4H, J=4.8 Hz), 3.95 (s, 2H), 6.78 (2H, d, J=9 Hz), 6.90 (2H, J=9 Hz), 7.48 (1H, s), 8.38 (1H, m), 8.80 (1H, m). MS (DCI/NH3) m/z 394 (M+H)+. Anal. Calcd for C19H18N3F3OS: C, 56.72; H, 4.76; N, 10.44. Found: C, 56.43; H, 4.50; N, 10.35.
