Participants

Reaction Steps

To a 25 mL round bottomed flask equipped with a magnetic stir bar, rubber septum, and argon inlet containing tert-butyl 1-azido-2-oxo-7,10,13-trioxa-3-azahexadecan-16-ylcarbamate (130 mg, 0.36 mmol), 6-(prop-2-ynyloxy)benzo[d]thiazole-2-sulfonamide (Alkyne, 107 mg, 0.4 mmol), CuI (6.9 mg, 0.036 mmol), and THF (3 mL) was added DIPEA (52 mg, 0.4 mmol). The mixture was stirred at rt for 15 h and concentrated. The crude material was purified with silical chromatography (gradient 10% to 90% EtOAc in hexane) to afford compound 142 as a clear wax (125 mg, 52%). MS (ESI) m/z 694(M+Na+).
