Reaction Steps

A mixture of 3-acetyl-7-chlorosulfonyl-2,3,4,5-tetrahydro-1H-3-benzazepine (4.0 g, 13.9 mmol), morpholine (1.8 ml, 20.8 mmol) and triethylamine (2.14 ml, 15.3 mmol) in tetrahydrofuran (120 ml) was heated at 60° C. for 3 h. The reaction mixture was then cooled, filtered and the filtrate evaporated in vacuo to give a yellow solid. Crystallisation from dichloromethane/n-hexane gave the title compound as an off-white solid (4.4 g, 94 Mass Spectrum AP+: Found 339 (MH+). C16H22N2SO4 requires 338.
