94-7. To a stirred solution of methyl 2-(7-(2-((tert-butoxycarbonyl)amino)acetyl)-4-chloro-5,6,7,8-tetrahydro-1,7-naphthyridin-8-yl)acetate (540 mg, 1.36 mmol) in MeOH (10 mL), 4N aqueous NaOH (0.39 mL, 1.56 mmol) was added and the solution was stirred at RT for 5 days. The solvent was evaporated under reduced pressure. The residue was dried under high vacuo overnight to yield the title compound as a beige powder (540 mg) which was used without further purification in the next step. UPLC-MS: MS 384.1 (M+H+); UPLC rt 0.81 min.
