Reaction Steps

7-Benzyl-4-chloro-5,6,7,8-tetrahydro-[1,7]naphthyridine (0.417 mmol) was treated with 5 equiv. of NaN3 (135 mg) in DMF (0.5 ml) and heated to 70° C. for 4 h. The residue was dissolved on 50 ml of DCM and washed with brine. The organic layer was concentrated to afford a black oil, which was purified by column chromatography to afford the desired azide (61 mg), which was used directly in the next step.
