Versuchsvorschrift

4-(2-Chloro-6-methanesulfonylamino-phenyl)-piperazine-1-carboxylic acid tert-butyl ester (145 mg, 0.37 mmol) was dissolved in 3 mL of CH2Cl2 and treated with 1.5 mL of trifluoroacetic acid. The reaction mixture was stirred at 25° C. for 1 h before all volatiles were removed. The solid was treated with CH2Cl2 (20 mL) and aqueous KOH (4 N, 10 mL). The organic layer was separated, dried over Na2SO4, and concentrated. The crude oil (90 mg) was dissolved in absolute EtOH (1.0 mL) and treated with 96 mg (0.24 mmol) of 5-methanesulfonyl-1-oxiranylmethyl-3-(4-trifluoromethyl-phenyl)-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine. The reaction mixture was refluxed at 85° C. for 3 h and then the solvent was removed. Column chromatography (silica, 0-5% MeOH/CH2Cl2) provided 138 mg (20% over 4 steps) of N-[3-chloro-2-(4-{2-hydroxy-3-[5-methanesulfonyl-3-(4-trifluoromethyl-phenyl)-4,5,6,7-tetrahydro-pyrazolo[4,3-c]pyridin-1-yl]-propyl}-piperazin-1-yl)-phenyl]-methanesulfonamide. TLC (silica, 5% MeOH/CH2Cl2): Rf=0.45. MS (electrospray): exact mass calculated for C28H34CIF3N6O5S2, 690.17; m/z found, 691.2 [M+H]+. 1H NMR (400 MHz, CDCl3): 8.28 (s, 1H), 7.65 and 7.59 (AB pattern, J=8.4 Hz, 4H), 7.36 (d, J=8.1 Hz, 1H), 7.07 (t, J=8.2 Hz, 1H), 6.9 (d, J=8.2 Hz, 1H), 4.54-4.44 (m, 2H), 4.21-3.94 (m, 3H), 3.77-3.52 (m, 4H), 3.41 (m, 2H), 2.96 (s, 3H), 2.81 (s, 3H), 3.05-2.73 (m, 4H), 2.66-2.20 (m, 4H).
