4-[1-Methyl-2,4-dioxo-6-(3-phenyl-prop-1-ynyl)-1,4-dihydro-2H-quinazolin-3-ylmethyl]-benzoic acid, PD0331179, was under investigation as a matrix metalloproteinase-13 inhibitor. 14C-labeled and 2H-labeled PD0331179 and its 2H-labeled metabolite (PD0335699) were required to support its preclinical and clinical studies. [14C] 3-phenyl-1-trimethyl/triphenylsilyl-propyne was efficiently prepared starting with [14C] benzoic acid and used as a key-labeled reagent for the synthesis of [14C] PD0331179. A one-pot coupling reaction between aryl iodide and trialkylsilyl propyne was developed to make this synthesis more efficient. The details of these syntheses are reported.

4-[1-甲基-2,4-二氧-6-(3-苯基-丙-1-炔基)-1,4-二氢-2H-喹唑啉-3-基甲基]-苯甲酸,PD0331179,正在作为基质金属蛋白酶-13的抑制剂进行研究。14C标记和2H标记的PD0331179及其2H标记代谢物(PD0335699)是支持其临床前和临床研究所需的。以[14C]苯甲酸为起始材料高效制备了[14C] 3-苯基-1-三甲基/三苯基硅基炔,并将其作为合成[14C] PD0331179的关键标记试剂。开发了一种芳基碘化物与三烷基硅基炔的一锅耦合反应,以提高合成效率。这些合成的具体细节已报告。版权 © 2012 John Wiley & Sons, Ltd.
