摘要
Human Factor Xa is a trypsin-like serine protease, which serves a critical role in blood coagulation events. LY517717 is currently under clinical investigation as a Factor Xa inhibitor. To support the ADME studies, LY517717 was synthesized using D-phenylglycine with a carbon-14 labeled carboxyl moiety. This key component, D-phenylglycine-[carboxyl-C-14], was synthesized by a Strecker synthesis on benzaldehyde with potassium [C-14]cyanide, followed by a resolution of DL-phenyl-glycine methyl ester-[carbonyl-C-14] with (+)-tartaric acid in the presence of benzaldehyde.
