Reaction Steps

A mixture of 3.1 g of (0.01 mole) of 4-chloro-6-methoxy-8-nitro-2-trifluoromethylquinoline, 75 ml of ethanol and 1 g of 5% Pd on CaCO3 was shaken on a Parr apparatus for 4.5 hr, at 50°-60°, under a hydrogen pressure of 70 psig. The yellow mixture was filtered and concentrated to dryness in vacuo. The residue was extracted with boiling ligroine (bp 90°-120° ) and the solvent was removed from the extract under reduced pressure. The residue was distilled to give 1.25 g (52%) of 8-amino-6-methoxy-2-trifluoromethylquinoline as a yellow oil, bp 127°-128° /1 mm.
