Reaction Steps

The product form step B above, 0.27 g (0.71 mmol) of (5S)-5-[(trityloxy)methyl]-6,7-dihydro-5H-pyrrolo[1,2-b][1,2,4]triazole, was dissolved in 35 mL of a 4.0 M solution of hydrogen chloride in anhydrous 1,4-dioxane. The reaction mixture was stirred for 10 min, quenched with 20 mL of methanol, then evaporated to dryness in vacuo. The residue was purified by reverse phase HPLC (TMC Pro-Pac C18; 0-90% 0.1% trifluoroacetic acid in acetonitrile/0.1% trifluoroacetic acid in water gradient) to yield the title compound (0.050 g, 50%). LC-MS: m/z (ES) 140 (MH)+.
