    • According to the method of the present invention, an alkali metal compound, dimethyl sulfoxide, trimethyloxosulfonium halide and 3-quinuclidinone are added in a specific order to give the following compound [II]. This compound is, without treatment or isolation, directly reacted with an alkali metal salt of phenothiazine to give the following compound [III], from which the following compound [I] is obtained. During the production of compound [I], a by-produced acidic gas is removed and water is added to ensure industrial, safe and efficient production of compound [I] at a constantly high yield. Inasmuch as the present invention enables production of the following highly pure compound [A] by eliminating hydrogen halide of compound [I] in glyme in the presence of at least one kind of a base selected from potassium hydroxide and potassium alkoxide, compound [A] having a high purity of not less than 85 mol % can be provided.
    • 根据本发明的方法,以特定的顺序加入碱金属化合物,二甲基亚砜,三甲基锍卤化物和3-奎宁环酮,得到下列化合物[II]。 该化合物在不经处理或分离的情况下与吩噻嗪的碱金属盐直接反应,得到以下化合物[III],由此得到下列化合物[I]。 在化合物[I]的生产过程中,除去副产的酸性气体,加入水以确保化合物[I]的工业,安全和有效的生产以不断的高产率。 由于本发明能够通过在至少一种选自氢氧化钾和醇钾的碱的存在下,通过除去甘醇二甲醚中的化合物[I]的卤化氢来制备下列高纯度化合物[A],化合物[A] 可以提供不小于85mol%的高纯度。
