- the measurement conditions for the powder X-ray diffraction pattern were as follows. (Measurement of powder X-ray diffraction pattern)
- the powder X-ray diffraction measurement of the crystals obtained in each example was performed according to the powder X-ray diffraction measurement method described in the Japanese Pharmacopoeia General Test Methods. Measurement conditions are shown below.
- Fig. 2 shows the results of the powder X-ray diffraction pattern of crystal A. Characteristic peaks are at 5.4°, 10.5° and 12.5°, more particularly at 5.4°, 7.7°, 10.5°, 12.5° and 14.5°. was 5°.
- Fig. 3 shows the results of the powder X-ray diffraction pattern of crystal B. Characteristic peaks are at 6.3°, 10.1°, 16.3° and 20.2°, more particularly 6.3°, 10.1°, 13.7°, 16.3° °, and 20.2°.
- Fig. 4 shows the results of the powder X-ray diffraction pattern of Crystal C. Characteristic peaks are at 6.8°, 17.4° and 19.8°, more particularly 6.8°, 10.1°, 12.7°, 17.4° and 19.8°. was 8°.
- Example 12-2 Measurement of pH 6.9 solubility Crystal B and crystal C were measured for pH 6.9 solubility. Specifically, an excess sample was added to the elution test second liquid (pH 6.9) (manufactured by Kanto Chemical Co., Ltd.) and shaken at 20° C. for 24 hours to prepare a saturated solution. After removing undissolved specimens with a filter, the amount of the compound in the filtrate was quantified by HPLC, and the solubility ( ⁇ g/ml) was calculated. As a result, the pH 6.9 solubility of Crystal B was 150 ⁇ g/ml. The pH 6.9 solubility of crystalline C was 25.0 ⁇ g/ml. From this, it can be seen that crystal B is good for applications that require high solubility.
- pH 6.9 solubility of Crystal B was 150 ⁇ g/ml.
- the pH 6.9 solubility of crystalline C was 25.0 ⁇ g/ml. From this, it can be seen that crystal B is good for applications that require high solub
- Example 12-3 Measurement of Hygroscopicity
- the hygroscopicity of Crystal B and Crystal C was measured with an automatic vapor adsorption measurement device (BELSORP Aqua3, manufactured by Microtrac Bell).
- BELSORP Aqua3 automatic vapor adsorption measurement device
- the maximum hygroscopicity of Crystal B was 1.35%.
- the maximum hygroscopicity of crystal C was 0.24%. From these results, it was found that any crystal form poses no particular problem in terms of hygroscopicity when used as a pharmaceutical composition. However, since crystal C has lower hygroscopicity, it can be said that crystal C is more preferable in this respect.
- Example 12-4 Measurement of Melting Points Crystal B and Crystal C were measured for their melting points using a thermal analyzer (8225A600, manufactured by Rigaku Corporation). As a result, the melting point of Crystal B was 151.9°C. The melting point of crystalline C was 182.5°C. From this, it can be seen that crystal C has a high melting point and is more preferable in terms of stability.
- Example 13 Preparation of crystal B with ethanol solvent Crystals B of compound I (5.93 g) and ethanol (24 mL) were added to a reactor and stirred at 70°C. It was then cooled to 45° C. and inoculated with 0.040 g of seed crystals. The seed crystal was obtained by the same procedure as the seed crystal used in Example 10. Then, the mixture was cooled to 30°C over 3 hours, cooled to 0°C over 3 hours, and stirred at the same temperature for 5 hours. The precipitated crystals were washed with ethanol. Crystals of compound I were thereby obtained. The crystal form of the obtained crystal was confirmed to be crystal A by powder X-ray diffraction pattern. Crystal A was dried under reduced pressure. This gave dry crystals of Compound I (5.25 g). The crystal form of the dried crystal obtained was confirmed to be crystal B by powder X-ray diffraction pattern.

After the reaction, water (2.3 mL) was added. The reaction solution was then concentrated under reduced pressure. Ethyl acetate (11.4 mL) and water (7.6 mL) were then added and the aqueous layer was extracted with ethyl acetate.
- step (e) Further, isopropanol (3.0 mL) was added and stirred at 35°C. After inoculating the reaction solution with 7.6 mg of seed crystals, the solution was stirred at the same temperature. As the seed crystal, the same one as used in Example 10 was used. After cooling the reaction solution to 20° C., isopropanol (6.1 mL) was added and the mixture was stirred at the same temperature. The precipitated crystals were washed with isopropanol. Furthermore, the crystals were dried under reduced pressure. This gave dry crystals of Compound I (1.10 g).
- Example 15 Preparation of compound I by one-pot method (steps (d)-(e)) Step (d-1) Compound 10-Boc (4.91 g) prepared in Example 6, acetonitrile (60 mL), sodium iodide (1.75 g), and chlorotrimethylsilane (2.11 g) were added to a reaction vessel and heated at 40°C. Stirred for 4 hours. The reaction solution was then cooled.
- Step (d-2) Then, compound 15 obtained in Example 9 (4.00 g), 1-hydroxybenzotriazole monohydrate (1.63 g), N- Methylmorpholine (2.94 g) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (2.05 g) were added and stirred at 30° C. for 1 hour. After the reaction, water (12 mL) was added. Further, the reaction solution was concentrated under reduced pressure. After that, ethyl acetate (56 mL) and 1N hydrochloric acid (40 mL) were added, and the aqueous layer was re-extracted with ethyl acetate. The organic layers were combined and washed successively with water, 8% sodium hydrogencarbonate aqueous solution twice, and 10% brine. The organic layer was filtered and the filtrate was concentrated. Ethanol (12 mL) was added to the concentrate and concentrated again.
- step (e) Further, ethanol (24 mL) was added and stirred at 45°C. After cooling to 30° C., the reaction solution was inoculated with 0.040 g of seed crystals and stirred at the same temperature for 1.5 hours.

続いて、ステップdにより、化合物Iを合成する。具体的には、スキーム(d-1)に従って、溶媒中で化合物10-R3を脱保護し、化合物16溶液を調製する(ステップd-1)。
上記の方法によれば、既述のように、取り扱いが難しい化合物16の塩酸塩を使用することなく、化合物Iを合成することができる。その結果、生産性を改善することができる。また、本実施形態に係る方法によれば、驚いたことに、合成された化合物Iを晶析により精製することができる。生産性に課題がある逆相HPLCを使用する必要がないので、この観点からも生産性が向上する。
まず、ワンポット法について説明する。ワンポット法では、ステップd-1とステップd-2とがワンポットで実施される。すなわち、ステップd-1で得られた化合物16溶液が、同じ反応容器に入れられたまま、ステップd-2において使用される。

溶媒としては、例えば、炭素数2~10のエーテル系溶媒が用いられ、テトラヒドロフランが好ましく用いられる。
接触還元法では、得られた化合物16溶液から触媒が除去される。触媒は除去されるものの、化合物16溶液から化合物16を単離する処理は実施されない。また、化合物16溶液の溶媒も除去されない。単に触媒の除去後の化合物16溶液を用いて、ステップ(d-2)が実施される。ステップ(d-2)は、ワンポット法と同様の方法により実施できる。
続いて、化合物(I)を、結晶化により、精製する。すなわち、結晶化溶媒中で化合物(I)を晶析させる。
この際に使用される溶媒としては、アセトニトリル、酢酸イソプロピル、ヘプタン、又はそれらの混合溶媒が好ましい。
本実施形態は、上述の方法により得られる化合物Iの結晶にも関する。すなわち、ステップ(e)において、化合物(I)を結晶化溶媒中で晶析させることにより、化合物(I)の結晶を得ることができる。
尚、ステップ(d)の後、単に溶媒を除去すれば、アモルファスの化合物(I)を得ることができる。

(粉末X線回折パターンの測定)
日本薬局方の一般試験法に記載された粉末X線回折測定法に従い、各実施例で得られた結晶の粉末X線回折測定を行った。測定条件を以下に示す。
(装置)
リガク社製 MiniFlex600-C
(操作方法)
測定法:反射法
使用波長:CuKα線
管電流:15mA
管電圧:40kV
X線の入射角:1.25°
ステップ幅:0.01°
スキャン範囲:2~60°
検出器:D/teX Ultra2
結晶B及び結晶Cについて、pH6.9溶解度を測定した。具体的には、溶出試験第2液(pH6.9)(関東化学社製)に、過剰の検体を添加し、20℃で24時間振とうさせて飽和溶液を作成した。溶け残った検体をフィルターで除去した後、ろ液中の化合物量をHPLCにて定量し、溶解度(μg/ml)を算出した。
その結果、結晶BのpH6.9溶解度は、150μg/mlであった。結晶CのpH6.9溶解度は、25.0μg/mlであった。このことから、高い溶解度が求められる用途については、結晶Bが良好であることが判る。
結晶B及び結晶Cについて、自動蒸気吸着測定装置(マイクロトラック・ベル社製、BELSORP Aqua3)で吸湿性を測定した。
その結果、結晶Bの吸湿性は、最大1.35%であった。一方、結晶Cの吸湿性は、最大で0.24%であった。この結果から、いずれの結晶形も、医薬組成物として使用するにあたり、吸湿性の点で特に問題のないものであった。但し、結晶Cの方が吸湿性がより小さいことから、この点でより好ましいと言える。
結晶B及び結晶Cについて、熱分析装置(リガク社製、8225A600)を用いて、融点を測定した。その結果、結晶Bの融点は151.9℃であった。結晶Cの融点は、182.5℃であった。このことから、結晶Cは、融点が高く、安定性という点からより好ましいことが判る。
反応容器に、化合物Iの結晶B(5.93g)、及びエタノール(24mL)を加えて、70℃で攪拌した。その後、45℃に冷却し、0.040gの種晶を接種した。なお、種晶は、実施例10で使用した種晶と同様の手順により取得した。
