Participants

Reaction Steps

A solution of N-t-butoxycarbonyl 7-(3-aminopropyl)-6-bromo-2-ethylbenzoxazole (396 mg, 1.03 mmol), vinyltributyltin (360 mg, 1.14 mmol), and tetrakis(triphenylphosphine)palladium (0) (60 mg, 0.052 mmol) in toluene (10 mL) was refluxed for 3 hours. The crude reaction mixture was poured directly on a silica gel column, and the tin by-products were eluted with hexanes. The product was eluted with 25% EtOAc/hexanes to give a clear oil (180 mg, 53%).
