The reaction of 2-(cyanomethyl)benzoic acid with amines RNH(2) (R = Ar, Het, CH(2)Ar, CH(2)Het) leads to the formation of the corresponding 3-NHR-isoquinolin-1(2H)-ones. When R = CH(2)Ar and CH(2)Het, there is a side reaction involving hydrolysis of the hydrolytically-unstable intermediates, derivatives of 2-(2-amino-2-iminoethyl) benzoic acid, leading to 2-R-isoquinoline-1,3(2H,4H)-diones.

A method to more quantitatively recover a peak of a protein and associated aggregates, hydrophobic proteins, or hydrophobic peptides which are typically difficult to recover and detect as a peak, using a commercially available gel filtration chromatography column and a mobile phase is described. More specifically, a compound, such as arginine, which may be added to the mobile phase, thereby eliminating the unnecessary interaction that occurs between the proteins, peptides, or aggregates and the column stationary phase is described.
