Reaction Steps

To a stirred solution of 86 mg (0.21 mmol) of 5-methanesulfonyl-1-oxiranylmethyl-3-(4-trifluoromethyl-phenyl)-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine in 4 mL of EtOH was added 50 mg (0.39 mmol) of 6-chloro-1-piperidin-4-yl-1H-indole. The solution was heated to 60° C. overnight. The solvent was then removed by rotary evaporation and the crude product was purified by column chromatography (silica, gradient elution from 0-5% 2 N NH3/MeOH in CH2Cl2) to afford 64 mg (48%) of a white solid. MS (electrospray), exact mass calculated for C30H33ClF3N5O3S: 635.19; m/z found, 636.2 [M+H]+. HPLC (reverse phase conditions 10-90%), tR=4.88 min. 1H NMR (CDCl3, 400 MHz): 7.72 and 7.67 (A and B of AB quartet, J=8.80 Hz, 4H), 7.52 (d, J=8.41, 1H), 7.34 (s, 1H), 7.18 (d, J=3.33 Hz,1H), 7.07 (dd, J=8.41, 1.76 Hz, 1H), 6.50 (d, J=3.33 Hz, 1H), 4.59 and 4.54 (A and B of AB quartet, J=14.48 Hz, 2H), 4.24 (dd, J=13.69, 2.39 Hz, 1H), 4.21-4.14 (m, 2H), 4.05 (dd, J=13.69, 6.46 Hz, 1H), 3.69 (m, 2H), 3.15 (brd, J=11.54 Hz, 1H), 3.11-2.91 (m, 3H), 2.60-2.48 (m, 3H), 2.28 (dt, J=11.74, 2.15 Hz, 1H), 2.13-1.93 (m, 4H).
