2-(2-(2-aminoacetyl)-5-bromo-6-fluoro-1,2,3,4-tetrahydroisoquinolin-1-yl)acetic Acid (HCl Salt). To a stirred solution of 2-(5-bromo-2-(2-((tert-butoxycarbonyl)amino)acetyl)-6-fluoro-1,2,3,4-tetrahydroisoquinolin-1-yl)acetic acid (58.45 g, 131 mmol) in dioxane (600 mL), 4N HCl in dioxane (328 mL, 1313 mmol) was added and the reaction mixture was stirred at RT for 24 h. The solvent was evaporated under reduced pressure and the HCl salt was dried under high vacuo overnight to yield the title compound as yellow foam (54.6 g). UPLC-MS: MS 345.2/347.2 (M+H+); UPLC rt 0.56 min.
