Reaction Steps

Using methyl 6-(1,1-dioxo-1λ6-isothiazolidin-2-ylmethyl)nicotinate (107 mg) described in Preparation Example 45 and 1-(5-ethyl-3-methylpyridin-2-yl)piperazine (81 mg) described in Preparation Example 81 and by the reaction and treatment in the same manner as in Example 109, [6-(1,1-dioxo-1λ6-isothiazolidin-2-ylmethyl)pyridin-3-yl][4-(5-ethyl-3-methylpyridin-2-yl)piperazin-1-yl]methanone (81 mg) was obtained. The obtained [6-(1,1-dioxo-1λ6-isothiazolidin-2-ylmethyl)pyridin-3-yl][4-(5-ethyl-3-methylpyridin-2-yl)piperazin-1-yl]methanone (81 mg) was dissolved in ethyl acetate/methanol, 2N hydrogen chloride/ethanol solution was added, and the solvent was evaporated under reduced pressure. The obtained residue was suspension washed with diisopropyl ether to give the title compound (83 mg).
