Reaction Steps

A mixture of 4.39 g of 5-(propan-2-yloxy)-3,4-dihydronaphthalen-1(2H)-one and 1.74 g of sodium azide in 70 ml of TFA is refluxed for 2 hours. The reaction medium is poured into 250 ml of water, brought to pH 7 by adding potassium carbonate and extracted with ethyl acetate. The organic phase is dried over magnesium sulfate, filtered and evaporated under reduced pressure. Purification is carried out by flash chromatography on silica gel (40-63 μm), elution being carried out with a mixture of dichloromethane and MeOH (100/0 to 90/10). 2.87 g of 6-(propan-2-yloxy)-1,3,4,5-tetrahydro-2H-1-benzazepin-2-one are obtained in the form of a beige solid.
