Conditions

Temperature: 50 °C

Procedure

Platinum(IV) oxide (30 mg) was added to a solution of 9-[4-(2-methylphenoxy)phenyl]-3,4-dihydropyrido[2,1-c][1,2,4]thiadiazine 2,2-dioxide (281 mg) in THF (dry) (150 mL) and MeOH (150 ml) and the mixture was stirred at 50° C. under hydrogen overnight. Activated carbon was added and the insoluble solid was removed by filtration through NH-silica gel/Celite pad (eluted with EtOAc). The filtrate was concentrated and the residue was crystallized from MeCN/IPE to give the title compound (144.1 mg) as colorless crystals.
