以(1-羟基-2-(1H-咪唑-1-基)乙烷-1,1-二基)二膦酸为原料合成1-羟基-2-(1-咪唑基)乙烷-1,1-二磷酸水合物的一般步骤如下： 实施例3：唑来膦酸一水合物的制备 将根据实施例1获得的原始潮湿唑来膦酸（相当于90.3g粗产物）悬浮于3050ml水中。在搅拌条件下，将悬浮液加热至回流状态。随后，加入EPO水使总体积达到3750ml，直至完全溶解。停止加热，继续搅拌，使溶液缓慢冷却至室温。当内部温度降至约70-80℃时，进一步冷却至2-5℃，并在此温度下维持1小时。过滤沉淀，并用冰水洗涤。将所得沉淀置于气流烘箱中干燥。最终，在5°C至60°C条件下获得169.3g（产率89%）无色晶体。通过热重分析（TGA）测得结晶水损失为6.8%，证实为一水合物。该物质的X射线粉末衍射（XRPD）图谱在2θ值为12.1°、12.8°、15.7°、18.9°±0.2°处显示特征峰，与已知晶型I（US 2005/0054616）的衍射数据一致。图1A展示了其XRPD图谱，图IV则展示了晶胞中原子的排列结构。
