トルエン30mLに実施例4で得た化合物(5a)10.81gを懸濁させ、アルゴン気流下、70℃でジイソプロピルエチレンジアミン(6)を滴下した後、100℃で5時間加熱攪拌した。反応液を放冷し、75℃で10%(w/w)塩化ナトリウム水溶液20mLを加え、抽出操作を行った。この操作をもう一度繰り返した。水層を除いた後、トルエンを減圧留去し、残渣を80%(v/v)2−プロパノール水38mLで希釈した。35%塩酸9.22gを滴下し、化合物(7a)塩酸塩を析出させた。析出結晶をろ取、2−プロパノールで洗浄後、50℃で減圧乾燥を行い、化合物(7a)の塩酸塩14.45gを収率97%で得た。

化合物(7c)の合成
20% 2−プロパノール水8mLに化合物(7a)2.0gを懸濁させ、加熱攪拌を行い、完全に溶解させた。攪拌を継続しながら放冷し、内温20℃で析出した結晶をろ取、20% 2−プロパノール水で洗浄した。50℃で減圧乾燥を行い、化合物(7c)1.8gを収率90%で得た。
得られた結晶(HCl・3H2O)は、カールフィッシャー法を用いた水分測定において、理論値9.98%に対し測定値9.99〜10.06%と3水和物を示唆するものである。湿度の変化、ならびに室温での取り扱いに対してその品質が変化せず安定であった。
