Reaction Steps

A solution of 3-aminobiphenyl-2-carbonitrile (4 g, 20 mmol) in ethanol (20 mL) and aqueous NaOH (8 g, 200 mmol) was heated at 100° C. in the microwave reactor for 1 h 30 min. After this time, the ethanol was evaporated under reduced pressure and the resulting residue was extracted with ethyl acetate. The organic extracts were concentrated under reduced pressure to yield a residue. The residue was purified by silica gel chromatography (50% EtOAc in hexane) to give 3-aminobiphenyl-2-carboxamide (3.1 g, 72% yield) as a brown solid. 1H NMR (400 MHz, DMSO-d6) δ (ppm): 7.40-7.30 (m, 5H), 7.15 (br s, 1H), 7.11 (t, 1H, J=8 Hz), 6.72 (dd, 1H, J=0.8, 8 Hz), 6.52 (dd, 1H, J=0.8, 8 Hz), 5.13 (s, 1H). LCMS Method W: retention time 1.28 min; [M+1]=213.0.
