丸いフラスコに結晶形遊離塩基化合物(12.9g、46.2mmol)を入れて窒素大気下でイソプロピルエーテル(300mL)に溶かした後、1M濃度の塩酸−イソプロピルエーテル溶液を0〜5℃で10分間加えた。反応物を0〜5℃で1時間撹拌して固体化合物を生成した。生成された固体化合物を窒素大気下で減圧濾過し、10℃以下に冷却させたイソプロピルエーテル(30mL)で洗浄した。洗浄された固体化合物をtert−ブチルエーテル:トルエン=1:1(50mL)に加えた後、窒素大気下で5〜10℃で激しく1時間撹拌して結晶を生成した。生成された結晶を濾過し、10℃以下に冷却させたtert−ブチルエーテル:トルエン=1:1の混合溶媒で洗浄し、40℃で12時間乾燥し、白色の結晶形塩酸塩化合物を得た。
丸いフラスコに2−プロピル−3−オキソ−3−フェニルプロピオン酸エチルエステル(5.6g、51.4mmol)、2−ヒドラジノピリジン(11.5g、49mmol)を入れ、反応溶媒無しで窒素大気下で3日間150℃で撹拌した。反応液を室温に冷却させた後に減圧濃縮し、ヘキサンとエチルアセテートで洗浄して真空乾燥させ、非結晶性遊離塩基化合物を得た。
丸いフラスコに前記比較例1で製造した非結晶性遊離塩基化合物(12.9g、46.2mmol)を入れてジエチルエーテル(300mL)に溶かした後、2M濃度の塩酸−ジエチルエーテル溶液を0〜5℃で10分間加えた。生成された固体化合物を減圧濾過し、ヘキサンとエチルアセテートで洗浄して真空乾燥させ、非結晶性塩酸塩化合物を得た。
結晶形3−フェニル−4−プロピル−1−(ピリジン−2−イル)−1H−ピラゾール−5−オル(結晶形遊離塩基)に様々な酸を付加して酸付加塩を製造した。結晶化方法としては、文献に公知された様々な方法、例えば反応性結晶化法(Reaction crystallization)、冷却結晶化法(Cooling crystallization)、ドラウニングアウト結晶化法(Drowning−out crystallization)、蒸発結晶化法(Evaporation crystallization)を利用した。20余種の酸を用いて結晶性酸付加塩化合物を製造し、それらのうち、蒸発結晶化法(Evaporation crystallization)を用いて製造された結晶形酸付加塩化合物を、下記表1に示した。
