실험 절차
Trifluoroacetic acid (2 mL) was added to a solution of tert-butyl 3-[[3-[(2S)-1-(difluoromethoxy) propan-2-yl]oxy-5-[5-(dimethylcarbamoyl)pyrazin-2-yl]oxy-benzoyl]amino]pyrazole-1-carboxylate (150 mg, 0.26 mmol) in DCM (16 mL) and stirred at RT for 2 hours. The solvent was removed in vacuo, DCM (20 mL) added and the mixture washed with water (20 mL), saturated sodium bicarbonate solution (20 mL), brine (20 mL), dried (MgSO4) and reduced in vacuo to give the desired compound (94 mg).
