実験手順
A suspension of tert-butyl 9-(2-fluorobiphenyl-4-yl)-9-methyl-3,4,6,7-tetrahydropyrazino[2,1-c][1,2,4]thiadiazine-8(9H)-carboxylate 2,2-dioxide (150 mg) and 4 N HCl/EtOAc (5 mL) in EtOAc (5 mL) was stirred at room temperature overnight. After removing solvent, the residue was recrystallized from MeOH to give the title compound (65 mg) as a white solid.
