Versuchsvorschrift

By an exactly analogous method to that described in Example 1, starting from 4-(2-methylimidazol-4-yl)benzoic acid hydrochloride and 1-(6-bromonaphth-2-ylsulphonyl)piperazine was prepared 1-(6-bromonaphth-2-ylsulphonyl)-4-[4-(2-methylimidazol-4-yl)benzoyl]piperazine (423 mg, 85% yield), m.p. 215-216° C. (from ethanol/hexane), 1H NMR (d6DMSO) 2.3 ppm (s,3H), 3.0-3.2 ppm (broad s,4H), 3.4-3.7 ppm (broad s,4H), 7.2 ppm (d,2H), 7.5 ppm (s,1H), 7.7 ppm (d,2H), 7.8 ppm (t,2H), 8.2 ppm (t,2H), 8.4 ppm (s,1H), 8.45 ppm (s,1H), 11.8 ppm (broad s,1H), the spectrum also contained signals due to ethanol (˜0.33 mol eq.); microanalysis, found: C, 55.4; H, 4.8; N, 9.9; S, 5.8%; C25H23N4O3BrS requires: C, 55.6; H, 4.5; N, 10.1; S, 5.8%; MS (M+H)+ 539/541.
