Methyl 2-aminopyridine-4-carboxylate → HCID 24811989, compound

Participants

Reaction Steps

To a solution of appropriate (4-adamantan-1-yl-phenoxy)-acetic acid (150 mg, 0.523 mmol), 2-amino isonicotinic acid methyl ester (159.3 mg, 1.04 mmol) and DMAP (127.9 mg, 1.04 mmol) in DMF (6 ml) was added PyBOP (545 mg, 1.04 mmol) at room temperature and the resulting mixture was stirred until reaction completion as indicated by TLC. Reaction mixture was poured onto ice cold water, diluted with ethyl acetate, separated organic layer and sequentially washed with aqueous sodium bicarbonate, brine and water, and dried over anhydrous MgSO4. The solvent was filtered and evaporated under reduced pressure to afford a crude solid, which was purified by flash chromatography on silica gel (EtOAc:hexanes=1:9 to 1:1) to afford of 2-[2-(4-adamantan-1-yl-phenoxy)acetylamino]-isonicotinic acid methyl ester as a colorless solid (0.166 g, 75% yield).
