Reaction Steps

A mixture of (9S)-9-(4-phenoxyphenyl)-3,4,6,7,8,9-hexahydropyrazino[2,1-c][1,2,4]thiadiazine 2,2-dioxide (129 mg), triethylamine (0.100 mL) and acetyl chloride (0.026 mL) in THF (4 mL) was stirred at 0° C. to room temperature for 20 hr. The reaction mixture was added with water, and the precipitate was filtered. The collected solid was purified by recrystallization from MeOH-EtOAc then preparative HPLC (C18, MeCN in H2O with 10 mM NH4HCO3). The combined collected fractions were concentrated in vacuo. The resulting solid was recrystallized from EtOAc—IPE to give the title compound (60 mg) as a white solid.
