Tri(butyl)vinyltin → HCID 68456961, compound

Participants

Reaction Steps

To a solution of (4-amino-5-iodo-2-methoxy-benzyl)-carbamic acid tert-butyl ester (700 mg, 1.85 mmol) and tributylvinyltin (783 mg, 2.68 mmol) in toluene was added Pd(PPh3)4 (214 mg, 0.19 mmol) under argon. The resulting mixture was heated with reflux for 8 hrs, filtered through celite, and then concentrated under reduced pressure. The crude residue was column-chromatographed (hexane/ethylacetate=2/1 to 1/1) to yield (4-amino-2-methoxy-5-vinyl-benzyl)-carbamic acid tert-butyl ester (220 mg, 43%).
