Procedure
In methanol (150 ml) was suspended methyl 7-cyclohexyl-1,2,4,5-tetrahydro-3-benzothiepin-5-one-2-carboxylate (40 g) followed by addition of 2N-KOH (100 ml), and the mixture was stirred at room temperature for one hour. The reaction mixture was then poured into water, acidified and extracted with etyl acetate. The ethyl acetate layer was washed with water, dried (MgSO4) and the solvent was distilled off to give 7-cyclohexyl-1,2,4,5-tetrahydro-3-benzothiepin-5-one-2-carboxylic acid (27.5 g, yield 72%). Recrystallization from ethyl acetate gave colorless plates.
