Procedure

Triphenylphosphine (0.25 g, 0.952 mmol) was added to a solution of (2R,5S,6S)-5-azido-6-hydroxy-2-methyl-azepane-1-carboxylic acid benzyl ester (0.193 g, 0.635 mmol) in THF (10 ml) and H2O (0.04 ml), then was heated to 45 degrees C. overnight. The reaction mixture was then diluted with toluene (100 ml×2) and was azeotroped in vacuo by rotary evaporation twice. The resulting oil was dissolved in MeOH and HCl in Et2O and the resulting salt was collected following filtration and was used in the next reaction without further purification (0.27 g, 90%).
