1-Methoxy-2-propanol → 3-Methyl-2-(4-quinolylamino)butanamide

Participants

Reaction Steps

4-Chloroquinoline (0.82 g, 5 mmol), valinamide (0.64 g, 5.5 mmol) and diisopropylamine (1.9 ml, 11 mmol) were mixed with 1-methoxy-2-propanol (8 ml) and heated with stirring at reflux for 48 hours. The solvent was removed under reduced pressure, the residue was partitioned between water and ethyl acetate, the phases were separated, the aqueous phase was washed 3 times with ethyl acetate and basified with 50% NaOH. A precipitate formed that was filtered off and dried in air to give 0.2 g of a solid (0.78 mmol, 14%). MS (APCI) M/z=243.6 [M+H]+.
