Reaction Steps

To diethyl-2-(2-(ethoxycarbonyl)-3-hydroxy-4-oxo-7,8,10,11-tetrahydro-4H-7,11-methanopyrimido[1,2-a][1,5]diazocin-9(6H)-yl)-2-butenedioate (0.300 g, 0.673 mmol) in acetonitrile (15 mL) was added trifluoroacetic acid (1 mL) at 23° C. The reaction mixture was stirred at 23° C. for 6 hours. CH3CN and trifluoroacetic acid were then removed in vacuo and the crude material was redissolved in toluene and dried again (2×30 mL) to afford 234 mg (90% yield) of the title trifluoroacetic salt. LCMS (+ESI, M+H+) m/z: 280.
