실험 절차

Platinum(IV) oxide (30 mg) was added to a solution of 9-[4-(3-methylphenoxy)phenyl]-3,4-dihydropyrido[2,1-c][1,2,4]thiadiazine 2,2-dioxide (357 mg) in THF (dry) (80 mL) and MeOH (80 mL) and the mixture was stirred at 50° C. under hydrogen for 6 hr. Activated carbon was added and the insoluble solid was removed by filtration through NH-silica gel/Celite pad (eluted with EtOAc) and the filtrate was concentrated in vacuo. The residue was crystallized from MeCN-THF/IPE to give the title compound (243.5 mg) as colorless crystals.
