Participants

Reaction Steps

A mixture of isonicotinic acid (1.00 g, 8.12 mmol), 2-aminoacetonitrile hydrochloride (0.902 g, 9.75 mmol), 1H-benzo[d][1,2,3]triazol-1-ol hydrate (1.24 g, 8.12 mmol), N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (1.71 g, 8.94 mmol) and N-ethyl-N-isopropylpropan-2-amine (4.95 ml, 28.4 mmol) in dichloromethane (20.3 ml, 8.12 mmol) was allowed to stir at room temperature for 24 hours. The mixture was concentrated and the residue was purified by CombiFlash using 0-10% methanol/DCM as the eluent to 1.31 g of N-(cyanomethyl)isonicotinamide 5.3B. 400 MHz 1H NMR (CDCl3) δ: 9.62 (br s, 1H), 8.87 (d, J=8.0 Hz, 2H), 7.94 (d, J=8.0 Hz, 2H), 4.30 (d, J=2H). LCMS (ES+) m/z 162.
