Procedure

Into a 50-mL 3-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed a solution of 3-(methylthio)-1-phenyl-6-(piperazin-1-yl)-1H-indazole hydrochloride (from Example 1, 80 mg, 0.22 mmol, 1.00 equiv) in N,N-dimethylformamide (10 mL), triethylamine (50 mg, 0.50 mmol, 2.10 equiv), 1-(tert-butoxycarbonyl)piperidine-3-carboxylic acid (60 mg, 0.26 mmol, 1.20 equiv), HATU (250 mg, 0.66 mmol, 3.00 equiv). The resulting solution was stirred overnight at room temperature. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:1) to yield tert-butyl 3-(1-(3-(methylthio)-1-phenyl-1H-indazol-6-yl)piperazine-4-carbonyl)piperidine-1-carboxylate as yellow oil. MS: 536 (MH+)
