Procedure

3-Cyclobutyl-7-{[6-(methyloxy)-3-pyridinyl]oxy}-2,3,4,5-tetrahydro-1H-3-benzazepine (E213a) (69 mg, 0.21 mmol) was dissolved in a solution of ethanol saturated with hydrogen chloride (5 ml). The reaction mixture was stirred at reflux for 18 hours, cooled and concentrated in vacuo. Purification of the resulting residue by column chromatography eluting with a mixture of 0.880 ammonia:methanol:dichloromethane (1:9:90) afforded the title compound (E213). MS (ES+) m/e 311 [M+H]+.
