Reaction Steps
A stream of HCl gas was bubbled into a suspension of tert-butyl 4-phenylpyridin-2-ylcarbamate (1–2, 0.93 g, 3.4 mmol, 1 equiv) in EtOAc (50 mL) at 0° C. for 2 min. The acidified solution was then heated at 60° C. for 3 h. The reaction mixture was cooled then concentrated to give 4-phenylpyridin-2-amine (1-3) as an off-white solid. LRMS m/z (M+H) Calcd: 171.2, found 170.9.
