本発明は、チオアミドに強塩基を添加し、次いでチオホルムアミドを反応させることを特徴とするが、このチオアミドの合成方法としては一例として以下の反応式(a)を利用することができる。
ベンジルアミン(12.0mL,0.11mol)のジメチルホルムアミド(DMF:50mL)溶液にベンズアルデヒド(10.1mL,0.1mol)を室温で加えた。ついで、硫黄(3.52g,0.11mol)を加え80〜90℃で6時間攪拌しながら加熱した。反応混合液をエチルエーテル(50mL)に注ぎ、有機相を飽和炭酸水素ナトリウム水溶液(200mL)、塩酸(35%,10mL)で洗浄した。さらに有機相を硫酸マグネシウムで乾燥させ、ろ過、減圧濃縮し、残渣をヘキサン/塩化メチレン(1:1,30mL)で再結晶して、化合物1を黄色固体として21.3g(収率:94%)を得た。
化合物1(0.227g,1.0mmol)をTHF(2.0mL)に溶解し、この溶液にn−ブチルリチウム−ヘキサン溶液(1.3mL,2.0mmol)を0℃で徐々に加えた。5分攪拌を行ったのち、N,N−ジメチルチオホルムアミドを同じ温度で加え、さらに2.5時間攪拌を続けた。反応混合液に水(10mL)を加え、有機相をジエチルエーテル(10mL)で抽出した。該有機相を水(10mL)で二回洗浄し、さらに水槽をジエチルエーテル(5mL)で再抽出した。集めた有機相を硫酸マグネシウムで乾燥させ、ろ過、減圧濃縮し、残渣をシリカゲルクロマトグラフィー(展開溶媒;Hexane:EtOAc:Et2N=5:1:0.01)で精製し、トランス−4,5−ジヒドロ−2,4−ジフェニル−5−ジメチルアミノチアゾール(0.14g,50%)を薄黄色固体として得た。
