A suspension of 3-bromo-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazine (Preparation 154, 29 mg, 0.143 mmol), K2CO3 (23.7 mg, 0.171 mmol), dimethyl sulfate (14 uL, 0.143 mmol in THF (3 mL) was stirred at 80° C. under microwave irradiation for 60 minutes. The reaction mixture was filtered and purified by elution through an SCX-2 column using 2M NH3/MeOH to give the title compound as yellow oil (16.5 mg, 53%).
