2,3,4,5-TETRAHYDRO-7-METHOXY-1H-BENZO[D]AZEPINE synthesis

13synthesis methods
-

Yield:50351-80-9 94%

Reaction Conditions:

with trifluoroacetic acid;sodium hydroxide in water at 20; for 4 h;

Steps:

4.1.5. General produce for the preparation of 2,3,4,5-tetrahydro-1Hbenzo[d]azepine

General procedure: Practical synthesis of regioisomeric 6- and 7-Methoxytetrahydro-3-benzazepines has been reported accordingto Organic Process Research & Development 2010, 14, 380e385.Removal of trifluoroacetyl could be effective with NaOH in THF/H2Omixed solution. The mixture was stirred at room temperature for4 h and extracted by ethyl acetate. The organic layer was thenconcentrated under reduced pressure and used for the next stepwithout further purification.
