Pirimiphos-methyl

<h2 id="synthesis">Synthesis</h2>
<p>Pirimiphos methyl is manufactured in a two-step process in which N,N-diethylguanidine is reacted with <a href="/facts/Ethyl_acetoacetate/AcfNjEgY">ethyl acetoacetate</a> to form a <a href="/facts/Pyrimidine/uFRSB8Cq">pyrimidine</a> ring and its <a href="/facts/Hydroxy_group/1Hs2QAEv">hydroxy group</a> is combined with <a href="/facts/Dimethyl_chlorothiophosphate/lyP6RpM6">dimethyl chlorothiophosphate</a> to form the insecticide.<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a>
</p>

<p>Pyrimiphos-ethyl is a related insecticide in which the <a href="/facts/Methoxy_group/KbrAmwQc">methoxy groups</a> are replaced with <a href="/facts/Alkoxy_group/6b40PtAp">ethoxy groups</a>.
