A solution of 3-(tert-butyloxycarbonyl)-7-hydroxy-2,3,4,5-tetrahydro-1H-3-benzazepine (3.0 g, 0.011 mol), methanesulfonylchloride (1.44 g, 0.013 mol), triethylamine (1.27 g, 0.013 mol) and dichloromethane (50 ml) was stirred at room temperature for 18 h. The reaction mixture was then partitioned between dichloromethane (50 ml) and a saturated solution of sodium hydrogen carbonate (50 ml). The organic layer was separated, washed with water (50 ml) and then dried (Na2SO4). The solvent was then evaporated in vacuo to give the title compound (3.85 g, 99%) as a pale yellow oil.
