Procedure

HCl in dioxane (4.0 M, 10 ml) was added to a stirred solution. [(3R,4R,7R)-3-Hydroxy-7-methyl-1-(pyridine-2-sulfonyl)-azepan-4-yl]-carbamic acid tert-butyl ester (0.6 g, 1.55 mmol) in MeOH (10 ml). The reaction mixture was stirred for 1 h at RT, then was diluted with toluene (20 ml), concentrated in vacuo by rotary evaporation and was used in the next reaction without further purification (0.5 g, quantitative): Electrospray mass spec: M+H+=286.2.
