Procedure

The method of Part B of Example 4 was used to hydrogenate 2-chloro-3-nitro-N-[(1R)-1-phenylethyl]quinolin-4-amine (24.35 g, 73.3 mmol) with the modifications that the reaction was stopped after one hour, and magnesium sulfate was added to the mixture before filtration. 2-Chloro-N4-[(1R)-1-phenylethyl]quinoline-3,4-diamine (21.0 g) was isolated as an amber oil.
