Participants

Reaction Steps

Lithium iodide (1.08 g; 8.04 mmole) was added to 1,3,4,5-tetrahydro-3-(methoxycarbonyl)-4-(methoxyphenyl)-3-(2-propenyl)-7-(trifluoromethyl)-2H-1-benzazepin-2-one (870 mg; 2.01 mmole) in pyridine (14 ml), three drops of water were added, and the mixture was refluxed with stirring for 6.5 hours. The solution was dissolved into ethyl acetate and washed with 1N hydrochloric acid (three times). The organic layer was dried (magnesium sulfate) and concentrated giving 0.79 g of solid. The crude material was used "as is" in the next step.
