chloropropiono-2',6'-xylidide (7.0 g, 0.033 mol), tis-octahydro-1//pyrindine HC1 (3.75 g, 0.03 mol), Na2C03 (7.5 g, 0.06 mol), and KI (0.1 g) in 4-methyl-2-pentanone (250 ml) was stirred and refluxed for 72 hr. After cooling, H20 was added. The organic layer was separated and dried (MgS04), and the solvent was removed in vacuo.The oily residue was converted into its HC1 salt in z-Pr20-HCl.Crystallization from z-Pr20-z-PrOH gave pure 11 (7.27 g, 72%), mp 202-203°. Anal. (C19H28N20'HC1) C, , 4,4a,5,6,7,8,(2//)-quinolinepropiono-2 ',6 -xylidide Hydrochloride (21). A suspension of 3chloropropiono-2',6'-xylidide (7.0 g, 0.033 mol), ds-decahydroquinoline HC1 (5.27 g, 0.03 mol), and NaHC03 (8.4 g, 0.1 mol) in EtOH (200 ml) was stirred and refluxed overnight. After cooling the mixture was concentrated in vacuo and 2 N aqueous HC1 was added.
