Reaction Steps

Diisopropylethylamine (2.3 mL) was added to a DMF solution (15 mL) of picolinic acid (814 mg), methyl 4-aminobenzenecarboxylate (1.0 g) and HATU (2.8 g), and stirred overnight at room temperature. Water was added to the reaction solution, and the resulting precipitate was taken out through filtration. The obtained residue was purified through silica gel column chromatography (chloroform/methanol=500/10 to 500/15) to obtain the entitled compound (1.4 g).
