実験手順
To a solution of 1.7 g (8.9 mmol) of 2,3,4,5-tetrahydro-1-benzoxepin-9-carboxylic acid in 5 ml of DMF is added 1.41 g(10.6 mmol) of N-chlorosuccinimide (NCS) in one portion at room temperature. The solution is stirred overnight and then diluted with ethyl acetate and washed with water. The organic layer is then dried (MgSO4), filtered and concentrated to obtain 7-chloro-2,3,4,5-tetrahydro-1-benzoxepin-9-carboxylic acid.
