Sodium hydride → HCID 5330112, compound

Participants

Reaction Steps

A mixture of sodium hydride (80 mg, 2.0 mmol) and 6-methoxy-7-fluoro-4-[(3,4,5-tri-methoxyphenyl)amino]-3-quinolinecarbonitrile (203 mg, 0.53 mmol) in 2-methoxyethanol (6 mL) is heated at reflux for 2 hours. Additional sodium hydride (80 mg, 2.0 mmol) is added and the reaction mixture is heated at reflux for 4 hours. The reaction mixture is cooled to room temperature and partitioned between ethyl acetate and saturated sodium bicarbonate. The organic layer is dried over magnesium sulfate, filtered and concentrated in vacuo. Trituration of the residue with ethyl acetate and diethyl ether provides 178 mg of 6-methoxy-7-[2-methoxyethoxy]-4-[(3,4,5-trimethoxyphenyl)amino]-3-quinolinecarbonitrile, mp 188-190° C.
