A mixture of 3-trifluoroacetyl-2,3,4,5-tetrahydro-1H-3-benzazepine-7-sulfonyl chloride (23 g, 67 mmol), potassium fluoride (12 g, 200 mmol), 18-crown-6 (0.1 g), and acetonitrile (100 mL) was stirred overnight. Water (200 mL) and ethyl acetate (200 mL) were added and the organic layer was washed with brine (100 mL), dried (MgSO4), and evaporated to give the title compound D1 as a white solid (21 g). 1H NMR 3 (d6-DMSO) 3.2 (4H, m), 3.7 (4H, m), 7.6 (1H, m), and 8.0 (2H, m).
