Procedure

4-(5-Morpholin-4-yl-1H-pyrrolo[2,3-c]pyridin-3-yl)-piperidine-1-carboxylic acid tert-butyl ester (180 mg, 0.47 mmol) was dissolved in 3.0 mL of CH2Cl2 and treated with 2.5 mL of trifluoroacetic acid. The reaction mixture was stirred at 25° C. for 1 h before all volatiles were removed. The solid was dissolved in MeOH (20 mL) and neutralized with DOWEX 550A OH anion exchange resin to pH 8. The resin was then filtered off and MeOH was removed under reduced pressure. The residue was dissolved in 2.5 mL of iPrOH and treated with 187 mg (0.47 mmol, 1 eq) of 5-methanesulfonyl-1-oxiranylmethyl-3-(4-trifluoromethyl-phenyl)-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine. The reaction was stirred at 85° C. for 3 h before solvent was removed. Column chromatography (silica, 5-10% MeOH/CH2Cl2 then 5-10% (2 N NH3 in MeOH)/CH2Cl2) provided 97 mg (30%) of the title compound. TLC (silica, 5% MeOH/CH2Cl2): Rf=0.25. MS (electrospray): exact mass calculated for C33H40F3N7O4S, 687.28; m/z found, 688.3 [M+H]+. 1H NMR (400 MHz, CDCl3): 8.47 (br s, 1H), 8.44 (d, J=1.0 Hz, 1H), 7.70 and 7.65 (AB pattern, J=8.4 Hz, 4H), 7.03 (d, J=2.1 Hz, 1H), 6.76 (s, 1H), 4.58-4.50 (m, 2H), 4.21-4.00 (m, 3H), 3.90 (t, J=4.5 Hz, 4H), 3.72-3.58 (m, 2H), 3.40 (t, J=4.5 Hz, 4H), 3.10-2.85 (m, 4H), 2.88 (s, 3H), 2.80-2.70 (m, 1H), 2.52-2.41 (m, 3H), 2.20-2.00 (m, 3H), 1.80-1.60 (m, 2H).
