The hypothesis is that hydroxychloroquine is noninferior to phlebotomy in terms of time to remission. Cost effective, semi-continuous flow methods and systems for synthesizing the antimalarial drug hydroxychloroquine HCQ in high yield are provided. The synthesis method that uses simple, inexpensive reagents to obtain the crucial intermediate 5-ethyl2-hydroxyethyl- aminopentan-2-one, vertical-integration of the starting material 5-iodopentan-2-one and the integration of continuous stirred. A metabolite of chloroquine – hydroxychloroquine – has a long half-life 32–56 days in blood and a large volume of distribution 580–815 L/kg. The therapeutic, toxic and lethal ranges are usually considered to be 0.03 to 15 mg/l, 3.0 to 26 mg/l and 20 to 104 mg/l, respectively.
