Reaction Steps

A solution of quinoline-4-carboxylic acid (173 mg, 1 mmol), and 1,1′-carbonyldiimidazole (162 mg, 1 mmol) in dimethylformamide (2 mL) was heated at 50° C. for 1 hour. After this time, trans-4-methylcyclohexylamine hydrochloride (150 mg, 1 mmol), and N,N-diisopropylethylamine (0.262 mL, 1.5 mmol) were added and the mixture heated at 50° C. for 16 hours. The reaction mixture was cooled, and diluted with chloroform (10 mL). The organic solution was washed with water (3×10 mL), 1 N NaOH (10 mL), brine (10 mL), dried over anhydrous MgSO4, filtered and concentrated to afford 224 mg (84%) of 404:
