Conditions

Temperature: 140 °C

Procedure

A mixture of 3-cyclobutyl-2,3,4,5-tetrahydro-1H-3-benzazepine-7-ol (E3) (84 mg, 0.385 mmol), 4-[(6-chloro-3-pyridazinyl)carbonyl]morpholine (E280, Step 1) (70 mg, 0.308 mmol) and potassium carbonate (85 mg, 0.616 mmol) in dry acetone (3 ml) was heated at 140° C. for 2×15 mins. (300 W) in a microwave reactor. The cooled reaction mixture was filtered, concentrated in vacuo. and Purified by column chromatography on silica gel, eluting with a mixture of 0.880 ammonia:methanol:dichloromethane (0.5:4.5:190) to afford the title compound; MS (ES+) m/e 409 [M+H]+.
