An improved method for the selective hydration of nitriles to amides employing N,N-disubstituted hydroxylamine is described leading to a reduction in reaction time and improved yield. Amides having electron-donating groups, which were not reported using the original method, were obtained in excellent yields. The amount of N,N-disubstituted hydroxylamine was reduced from three equivalents to one equivalent
The present invention provides compounds and compositions thereof which are useful as inhibitors of plasma kallikrein and which exhibit desirable characteristics for the same.
