Kepner-Tregoe Decision Analysis as a Tool To Aid Route Selection. Part 2. Application to AZD7545, a PDK Inhibitor
摘要:
Kepner-Tregoe decision analysis was formally used as an aid to route selection, as outlined in the preceding paper. Over 40 paper routes were assessed for suitability for both immediate and longer term manufacture of AZD7545, a compound in the early stages of development. Eight routes were then investigated in fall in the laboratory, and a further four in part, over a period of 3-4 months. From this exercise, the preferred long-term manufacturing route was identified before the first pilot scale manufacture had been completed. This route selection exercise worked well in this case where a large number of potential routes had to be considered using limited resources. It was also an effective means of bringing some long-term manufacturing issues to the fore at an early stage in development.

requirement of higher reaction temperatures for an SNAr reaction between thiols and less reactive electron-poor aryl halides described in earlier reports has triggered intensive studies on the development of metal- and photo-catalyzed methods to promote this transformation. We report here that an SNAr reaction of thiols with most electron-poor aryl halides takes place at RT–60 °C under the action of
早期报道中描述的硫醇和反应性较低的缺电子芳基卤化物之间的S N Ar 反应需要更高的反应温度,这引发了对开发金属和光催化方法以促进这种转变的深入研究。我们在此报告,在 K 2 CO 3和 DMAc的作用下,硫醇与大多数缺电子芳基卤化物在 RT–60 °C 下发生S N Ar 反应。在这种温和的条件下,碱和溶剂都起着至关重要的作用。对于对 S N不发生反应的(杂)芳基卤化物Ar反应中,鉴定出两种更强大的草酸二酰胺配体,使其Cu催化的偶联反应能够在低催化负载量下进行。这两种方法的结合为制备(杂)芳基硫醚提供了一种非常有吸引力的方法。

manufacturing routes to AZD7545 is given. Processdevelopment of the preferred long-term manufacturing route is reported in detail, and changes from the initial kilogram-scale route are discussed. Scale-up experience from the pilot-plant manufacture is included in the discussion of each stage. Noteworthy aspects throughout the development of AZD7545 concerned chemical hazards, mechanisms, analysis, and impurities
