また、上記は水添加速度の数値に基づいて内挿したものであるが、本発明の目的が達成される範囲において、r<0.007、r>0.01175(単位はmL/分/mL)に外挿してもよい。この場合も同様に、適宜定めた前提条件の水添加速度に基づいて他の具体的条件を容易に計算できるから、その外挿範囲が本発明の目的を達するものであるかどうかは、当業者であれば試行により容易に判断することができる。
[実施例1]
0.024mol/Lの2−(3−シアノ−4−イソブチルオキシフェニル)−4−メチル−5−チアゾールカルボン酸のメタノール/水(95/5)溶液を調製し、その40mLに、内温を40℃に保ちながら0.28mL/分の速度で水を14.2mL添加した。水の添加中、40分経過した時点で種晶(A晶)を10mg添加した。析出した結晶をろ取したのちに乾燥した。得られた結晶の粉末X線回折を行ったところ、A晶であった。また、種晶の添加量を20mgから40mgに変化させても同様にA晶が得られた。
Claims (1)
- 2−(3−シアノ−4−イソブチルオキシフェニル)−4−メチル−5−チアゾールカルボン酸をメタノールまたはメタノール/水混合溶媒(ただしメタノール/水の容量比は90/10以上)に溶解し、次に水をメタノール/水の比率が7/3になるまで40℃以下の状態を保ちながら添加し、さらにかかる水添加中の特定の時期に特定量の種晶を加えることにより2−(3−シアノ−4−イソブチルオキシフェニル)−4−メチル−5−チアゾールカルボン酸のA晶を製造する方法であって、初期濃度が0.024±0.008mol/L、水添加速度が0.007mL/分/mLのとき、種晶添加量および種晶添加時間を図1の領域Iで示される条件とすることを特徴とする方法。
