Procedure
Using (S)-3-benzyloxymethylisothiazolidine 1,1-dioxide (287 mg) described in Preparation Example 1 and [4-(3,5-dimethylpyridin-2-yl)piperazin-1-yl](4-iodophenyl)methanone (500 mg) described in Preparation Example 113 and by the reaction and treatment in the same manner as in Example 1, (S)-[4-(3-benzyloxymethyl-1,1-dioxo-1λ6-isothiazolidin-2-yl)phenyl][4-(3,5-dimethyl-pyridin-2-yl)piperazin-1-yl]methanone (490 mg) was obtained. The obtained (S)-[4-(3-benzyloxymethyl-1,1-dioxo-1λ6-isothiazolidin-2-yl)phenyl][4-(3,5-dimethyl-pyridin-2-yl)piperazin-1-yl]methanone (490 mg) was dissolved in ethyl acetate, 4N hydrogen chloride/ethyl acetate was added, and the precipitate was collected by filtration to give the title compound (410 mg).
