Reaction Conditions

Reaction Steps

A solution of nicotinic acid (42 mg, 0.34 mmol) and 1,1′-carbonyldiimidazole (72 mg, 0.44 mmol) in N,N-dimethylformamide (1.5 mL) was stirred at 70° C. After stirring at 70° C. for 1 h, a solution of 2-(3-amino-phenyl)-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (100 mg, 0.34 mmol) in N,N-dimethylformamide (2 mL) was added and the mixture was allowed to stir at 25° C. for 1 h. Purification by Waters automated flash system (column: Xterra 30 mm×100 mm, sample manager 2767, pump 2525, detector: ZQ mass and UV 2487, solvent system: acetonitrile and 0.1% formic acid in water) afforded 3,3-dimethyl-2-{3-[(pyridine-3-carbonyl)-amino]-phenyl}-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (21 mg, 15%) as a white solid: LC/MS m/e calcd for C24H23N3O3 (M+H)+: 402.47, observed: 402.1.
