2-アセトキシ-5-(α-シクロプロピルカルボニル-2-フルオロベンジル)-4,5,6,7-テトラヒドロチエノ[3,2-c]ピリジン(2g)を酢酸(20ml)に溶解し、25℃の室温で攪拌しながら、酢酸に溶解した臭化水素(40%)の溶液(1.1g)を混合物に滴下した。少量の種結晶を溶液に添加し、ついで混合物を2時間室温で攪拌した。得られる結晶は濾過により分離され、少量のアセトンで洗浄され、次いで減圧下で4時間60℃で乾燥され、白い結晶として表題の化合物を得た(2.29g、収率83%)。
プラスグレル臭化水素酸塩の酢酸溶媒和物(0.4g)を酢酸(4ml)に溶解し、混合物を70℃に加熱した。混合物を10分間攪拌し、次いで自然に室温へ冷却した。混合物は別途2時間攪拌した。得られた結晶を濾過により分離し、少量のアセトンで洗浄し、次いで、減圧下で4時間60℃で乾燥させて、白い結晶として表題の化合物を得た(0.34g、収率85%)。
2-アセトキシ-5-(α-シクロプロピルカルボニル-2-フルオロベンジル)-4,5,6,7-テトラヒドロチエノ[3,2-c]ピリジン(2g)をアセトン及び酢酸の混合物(30ml)に溶解し、酢酸に溶解した臭化水素(40%)の溶液(1.1g)を0℃で攪拌しながら滴下した。少量の種結晶を添加し、次いで混合物を同じ温度で2時間攪拌した。得られた結晶を濾過により分離し少量のアセトンで洗浄し、次いで減圧下で4時間60℃で乾燥させて、白い結晶として表題の化合物を2.31g得た。

試料:実施例2の酢酸溶媒和結晶(結晶A)
X線粉末回折試験:機器型:Bruker D8 ADVANCE;光源:Cu−Kα 40kV 40mA;グラファイトモノクロメーター;発散スリット(DS):1°;散乱線除去スリット(SS):1°;リンクスアイアレイ検出器、走査方式:θ/θ、連続走査;走査範囲:3°〜45°、走査速度:8°/min。結果を図1に示す。
赤外線吸収スペクトル試験:米国NICOLET社の670FI−IR分光計を使用、ヌジョール法、走査範囲:400〜4000cm-1。結果を図2に示す。
熱重量分析(TGA)試験:NETZSCH TG 209F1を使用し、試験条件は以下の通りであった。酸化アルミニウムのルツボを使用し、窒素置換下で10℃/分の温度上昇速度で走査範囲は25℃から300℃であった。結果を図3に示す。180℃までに失われた重量は試料中の酢酸の重量である。図3から計算できる通り、実施例2の試料中において酢酸のプラスグレル臭化水素酸塩に対するモル比は約1:1である。
DSC試験:機器:NETZSCH DSC 204 F1;温度上昇速度:30°から250°で10.0K/分。結果を図4に示す。
試料:実施例3の酢酸溶媒和結晶(結晶A)
X線粉末回折試験:機器型:Bruker D8 ADVANCE;光源:Cu−Kα 40kV 40mA;グラファイトモノクロメーター;発散スリット(DS):1°;散乱線除去スリット(SS):1°;リンクスアイアレイ検出器、走査方式:θ/θ、連続走査;走査範囲:3°〜45°、走査速度:8°/min。結果を図5に示す。
図1のピーク位置、ピーク強度及びピークの形は図5のそれらと良く合致し、従って実施例2及び3の結晶は同一である。2つのスペクトルは幾つかの場所でお互いわずかに異なり、それらは実験誤差及び様々なバッチにおける結晶化度の違いに起因しうる。
実施例3における指数付け及びもとの粉末回折分光写真の修正により得られた格子定数は以下の通りである(かっこ内の数字は統計誤差である)。結晶は斜方晶系構造に属し、その空間群はPnma(62)。a=15.32642(0.000202)Å;b=7.38783(0.00637)Å;c=20.81522(0.000096)Å;α=β=γ=90°、及びその格子体積=2356.89Å3である。
角度誤差│△2θ│=0.0058°;原点オフセット=0.0°;線質係数F(30)=45.3(110)。
少ない角度誤差、原点オフセット無し、及び良く合致した実験及び理論によるスペクトル線の位置に基づいて、指数付けの結果は信頼性が高い。
結果は、提供された試料は純粋な相化合物で、対応する実験の分光写真はデータとして及び同一相を識別するための指紋として使用できることを示している。
試料:実施例6の非溶媒和結晶(結晶B)
X線粉末回折試験:機器型:Bruker D8 ADVANCE;光源:Cu−Kα 40kV 40mA;グラファイトモノクロメーター;発散スリット(DS):1°;散乱線除去スリット(SS):1°;リンクスアイアレイ検出器、走査方式:θ/θ、連続走査;走査範囲:3°〜45°、走査速度:8°/min。結果を図6に示す。
図1及び6の間でピーク位置、ピーク強度及びピーク形状に著しい違いがあり、従って実施例6及び2の結晶は異なる。
実施例6における指数付け及びもとの粉末回折分光写真の修正により得られた格子定数は以下の通りである。結晶は斜方晶系構造に属し、その空間群はPnma(62)。a=15.42456Å;b=7.28661Å;c=21.23884Å;α=β=γ=90°、及び格子体積=2387.09Å3。線質係数F(30)=25.4(117)。
結晶A及びBについて:(1)結晶Bの分子は結晶Aのそれより一酢酸分子少なく、従って分子量もより少ない、しかしながら、酢酸分子とプラスグレル分子の間に水素結合が形成され、結晶Aのよりコンパクトで整った空間構造をもたらすため、結晶Bの格子体積は結晶Aのそれより大きい。安定性試験において、結晶Aの安定性は結晶Bより良い。安定性の違いは空間構造の違いによる。
