(±)-tert-Butyl 4-((1-(5-cyclopropyl-1H-indazol-7-yl)ethoxy)methyl)-4-(4-fluorophenyl)piperidine-1-carboxylate (30 mg, 0.061 mmol) was dissolved in trifluoroacetic acid (20% in dichloromethane, 2 mL) and stirred at room temperature for 30 min. The reaction was concentrated and loaded onto a strong cation exchange cartridge in methanol. The cartridge was flushed with several volumes of methanol which were discarded. The product was eluted with 2 M ammonia in methanol and concentrated to give 21.8 mg (91%). LC/MS (HPLC method 3): tR=2.235 min, 394.10(MH)+.
