Methods and materials for preparing quinapril, its pharmaceutically acceptable salts, including quinapril hydrochloride, are disclosed. The method includes reacting (2S,4S)-2-(4-methyl-2,5-dioxo-oxazolidin-3-yl)-4-phenyl-butyric acid ethyl ester with (3S)-1,2,3,4-tetrahydro-isoquinoline-3-carboxylic acid tert-butyl ester to yield quinapril tert-butyl ester, which is subsequently reacted with an acid to yield quinapril or an acid addition salt of quinapril.

A process for the production of amides of N-[1-(S)-(ethoxycarbonyl)-3-phenylpropyl]-L-alanine is described. The process can be used for the production of key intermediates and finally the ACE inhibitors such as Ramipril, Enalapril, Quinapril, Trandolapril, Delapril and Moexipril starting from N-[1-(S)-(ethoxycarbonyl)-3-phenylpropyl]-L-alanine by the reaction with the appropriate amines.

The synthesis and angiotensinconvertingenzyme (ACE) inhibiting activities of quinapril (CI-906, 22), its active diacid (CI-928, 33), and its dimethoxy analogue (CI-925, 25) are reported. These tetrahydro-3-isoquinolinecarboxylic acid derivatives possess equivalent in vitro potency and in vivo efficacy to enalapril. Sulfhydryl analogues with the same structural variation are also highly potent. In

angiotensin converting enzyme (ACE) inhibitors is described. An optimization effort guided by in situ IR analysis resulted in a general amide coupling approach facilitated by N-carboxyanhydride (NCA) activation that was further characterized by reaction kinetics analysis in batch. The three-step continuous process was demonstrated by synthesizing 8 different ACE inhibitors in up to 88 % yield with throughputs
