Reaction Steps
In the final step of this novel process, an aniline 10 is treated with a ketone 11, especially acetone, cyclohexanone or 3-pentanone, in the presence of a catalyst, especially camphor sulfonic acid, boron trifluoride etherate or lanthanum tris(trifluoromethanesulfonate), to afford the 1,2-dihydroquinoline 12:
