2-[[(4S)-4-aminopentyl]-ethylamino]ethanol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: (S)-(+)-Hydroxychloroquine was prepared by condensing (S)-(+)-2-[(4-aminopentyl)ethylamino]ethanol with 4,7-dichloroquinoline. The latter compound is known. The (S)-(+)-2-[(4-aminopentyl)ethylamino]ethanol was prepared by resolving known racemic 2-[(4-aminopentyl)ethylamino]-ethanol by forming a salt thereof with known (S)-(+)-mandelic acid and separating the (S)-(+)-mandelic acid salts of the two enantiomers by crystallization. by forming a salt with known (S)-(+)-mandelic acid and separating the (S)-(+)-mandelic acid salts of the two enantiomers by crystallization
