Reaction Steps

Using General Procedure B: Reaction of 8-amino-4-methoxy-5,6,7,8-tetrahydroquinoline (0.297 g, 1.67 mmol) and 4-(1,3-Dioxo-1,3-dihydro-isoindol-2-yl)-butyraldehyde (0.371, 1.71 mmol) with NaBH(OAc)3 (0.493 g, 2.33 mmol) in CH2Cl2 (8 mL) for 60 minutes followed by purification of the crude material by column chromatography on silica gel (20:1 CH2Cl—2—CH3OH) provided 0.345 g (54%) of 2-[4-(4-Methoxy-5,6,7,8-tetrahydro-quinolin-8-ylamino)-butyl]-isoindole-1,3-dione as an off-white solid.
