  使用NaHMDS作为碱，在THF中用碘甲烷将4-甲氧基-1 H-吡唑并[3,4- d ]嘧啶（1b）烷基化，选择性地提供了N2-甲基产物4-甲氧基-2-甲基-2 H-吡唑并[3，相对于N1-甲基产物（2b），以8/1的比例存在4- d ]嘧啶（3b）。有趣的是，在DMSO中进行反应使选择性逆转，以提供4/1的N1 / N2甲基化产物比例。产品3b的晶体结构N1和N7与钠配位表明后者可能增强N2选择性。用26个杂环测试了选择性极限，结果表明，当在THF中进行反应时，N7是控制烷基化的控制元素，对于吡唑并环而言，该环对吡唑并环反应有利于N2，对咪唑和三唑并稠合的环杂环则有利于N3。使用1个H-检测脉冲场梯度受激回波（PFG-STE）NMR确定的离子反应性复合物的分子量。该数据和DFT电荷分布计算表明，紧密离子对（CIP）或紧密离子对（TIP）控制THF中的烷基化选择性，而溶剂分离的离子对（SIPs）是DMSO中的反应性物质。
