実験手順

A solution of 6-((benzyloxy)carbonyl)picolinic acid (3.0 g, 11.7 mmol) in saturated NH4OH (100 mL) was heated in a sealed tube at 90° C. for 6 h and monitored by TLC (CHCl3/MeOH 8:2 v/v). The reaction mixture was evaporated to dryness to get the 6-carbamoylpicolinic acid (1.8 g, yield 94%) as a white solid, which was carried through without further purification. MS (ESI) m/z: Calculated for C7H6N2O3: 166.04. found: 167.0 (M+H)+.
