All this is not very promising and any attempt to optimize this reaction is fighting problems you would not have if you had decided for a more reasonable and well-established alternative in the first! A quick-and-dirty electrostatic potential calculation using B88LYP/6-31G(d) on the PM3 geometry shows a large electron density (blue and violet) on the ring nitrogen and lower density (yellow) on the exocyclic amine: Are there conditions that might work? That would be the synthesis of chloroquine from 4,7-dichloroquinoline and 4-diethylamino-1-methylbutylamine, where both starting materials are available through well-known procedures.

    It's a pretty untypical approach to chloroquine and you didn't tell how you would synthesize 7-chloro-3-aminoquinoline and the secondary chloride. There is a good chance that the planned reaction will furnish a quarternary ammonium salt as a side product: The reaction will not necessary stop at this point.

    Hydroxychloroquine dosage recommendations often ignored. Based on the 2011 recommendations from the AAO and ACR, 17% of the patients were receiving an HCQ overdose that was more than 10% above the recommended dosage, and another 13% received a smaller overdose. If the 2016 dosage guidelines were applied, the extent of overdosing might be even greater, Dr. Koppikar said.
