Procedure

A suspension of tert-butyl 9-(2-fluorobiphenyl-4-yl)-3,4,6,7-tetrahydropyrazino[2,1-c][1,2,4]thiadiazine-8(9H)-carboxylate 2,2-dioxide (0.71 g), iodomethane (0.115 ml) and NaH (60%, 93 mg) in DMF (16 mL) was stirred at 0° C. to room temperature overnight. The reaction mixture was added with water and extracted with EtOAc. The organic layer was washed with brine and water, dried over anhydrous magnesium sulfate and concentrated. The residue was purified by column chromatography (silica gel, eluted with EtOAc in hexane). The obtained material was purified by column chromatography (silica gel, eluted with EtOAc in hexane) to give the title compound (150 mg) as a white solid.
