Reaction Steps
In analogy to the procedures described for the preparation of intermediates A-2 [B] and A-2 [C], (rac)-6-bromo-2,3-dihydro-benzofuran-3-ol was treated with diphenylphosphoryl azide, DBU in toluene to give (rac)-3-azido-6-bromo-2,3-dihydro-benzofuran, which was subsequently reduced with triphenylphosphine in THF/water to yield the title compound as light yellow oil. MS: 213 (M+, 1Br).
