Procedure

A mixture of 9-(4-phenoxyphenyl)-3,4-dihydropyrazino[2,1-c][1,2,4]thiadiazine 2,2-dioxide (96.0 mg), and platinum(IV) oxide (15.0 mg) in EtOH (5 mL) was stirred at room temperature for 2.5 hr under H2. The mixture was added with NH silica gel, concentrated, purified by column chromatography (NH silica gel, eluted with MeOH in EtOAc), then recrystallized from EtOAc—IPE to give the title compound (32.0 mg) as white powder.
