Reaction Steps

To a mixture of 1-(4-benzyloxy-phenyl)-2-bromo-ethanone (28.55 g; 93.6 mmol) in CH2Cl2 (300 mL) and water (30 mL) was added nBu4NBr (1.51 g; 4.7 mmol) and NaN3 (6.69 g; 102.9 mmol) in one portion. After 4 h at RT, the layers were separated. The organic layer was washed water, dried (Na2SO4), filtered and concentrated in vacuo to afford 2-azido-1-(4-benzyloxy-phenyl)-ethanone (23.64 g).
