(1S,4S)-2lambda6-thia-5-azabicyclo[2.2.1]heptane 2,2-dioxide

Conditions: temp:120.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of (1S,4S)-2-thia-5-azabicyclo[2.2.1]heptane 2,2-dioxide (65 mg, 0.442 mmol), potassium phosphate (375 mg, 1.766 mmol), 2-bromoethanol (221 mg, 1.766 mmol) and potassium iodide (147 mg, 0.883 mmol) in acetonitrile (2 mL) was heated up at 120° C. for 4 hours. The reaction mixture was concentrated under reduced pressure and purified in silica gel with 0-15% methanol/ethyl acetate to provide the title product (60 mg, 71% yield) as a white solid. LCMS: m/e 192.07 (M+H)+, 0.87 min (method 2) The reaction mixture was concentrated under reduced pressure purified in silica gel with 0-15% methanol/ethyl acetate
