This example provides an example of a small-scale crystallization of Forn I the besylate salt of compound 101 from the free base of compound 101.Compound 101 was recrystallized as Form I with benzenesulfonic acid (PhSO3H-xH2O;Aldrich).3.9g benzenesulfonic acid was dissolved in 5 ml ethanol,and this ethanol solution was added to 5.02g solid free base compound101.For this example,compound 101 was prepared according to Example 1,except that an SnCl2 reduction was used for reduction of compoundⅡto compound Ⅲ.The mixture was rinsed with 5 ml ethanol,and additional ethanol was further added to a total of 25 ml.The mixture was heated to form a complete solution and then slowly cooled with stirring.Solid Form I,5.57g,was collected by filtration and rinsed with ethanol.

请先检查一下英文文段的正确性.前两句话好像有问题,单词拼写有误,语法不通.(我不是学化工的,只能根据字面意思翻译,如有错误,请见谅.)
这个样本提供了一个从101号化合物自由基中提取少量1型苯磺酸盐结晶的范例.当与苯磺酸钠反应,101号化合物就再度结晶为1型物质.(PhSO3H-xH2O;Aldrich).将3.9克苯磺酸钠溶解在5毫升酒精中,再将该酒精溶液添加到5.02克固体101号化合物自由基中.对于这个样本来说,除了有一个氯化亚锡的还原反应是为了将2号化合物还原为3号化合物,101号化合物都是为1号样本准备的.用5毫升酒精冲洗混合物,额外使用的酒精量总计25毫升.将混合物加热,使其完全溶解,再缓慢搅动使其冷却.过滤,并用酒精冲洗,5.57克的1型结晶就提取完成了.
