EXAMPLE 3; Example 3A; 1 -f 2.4-difIuorophenyl)-4-(2-naphthv1sulfonyl)rhoiperazine; Step 3A; To a stirred solution of naphthalene-2-sulfonyl chloride (350 mg, 1.54 mmol) and l-(2,4-difluororhohenyl)piperazine (305.0 mg, 1.54 mmol) in anhydrous dichloromethane (5 mL) was added diisopropylethylamine (0.670 mL, 3.85 mmol). The mixture was stirred for 30 minutes. Reaction was complete as determined by TLC. The reaction mixture was purified via flash column chromatography to afford l-(2,4-difluorophenyl)-4-(2-naphthylsulfonyl)piperazine in 55% yield (327 mg) as white solid.IH NMR (400 MHz, DMSO-D6) delta ppm 3.00 – 3.07 (m, 4 H) 3.07 – 3.15 (m, 4 H) 6.94 – 7.02 (m, 1 H) 7.03 – 7.12 (m, 1 H) 7.12 – 7.21 (m, 1 H) 7.67 – 7.84 (m, 3 H) 8.11 (d, J=8.08 Hz, 1 H) 8.21 (d, J=8.59 Hz, 1 H) 8.25 (d, J=8.08 Hz, 1 H) 8.49 (d, J=I.77 Hz, 1 H). HRMS: calcd for C20H18F2N2O2S + H+, 389.11298; found (ESI-FTMS, [M+H]l+), 389.113. HPLC Method 1: room temperature, 6.658 min, 96.32%, HPLC Method 2: room temperature, 7.312 min, 99.29%., 115761-79-0
As the paragraph descriping shows that 115761-79-0 is playing an increasingly important role.
