Reaction Steps

As shown in Reaction 4, Compound III may be reacted with lithium aluminum hydride (LAH) in tetrahydrofuran (THF) to produce 5-ethoxyheptanol (Compound IV). Compound IV may be produced at a yield of from approximately 90% to approximately 99%. The reaction may be conducted at a temperature of from approximately −50° C. to approximately room temperature (from approximately 20° C. to approximately 25° C.). To control the reaction, in some embodiments, the reaction is conducted at room temperature. As shown in Reaction 5, Compound IV may be reacted with methanesulfonyl chloride (MSCl) and pyridine in dimethylformamide (DMF) to produce 1-chloro-5-ethoxyheptane (Compound V) at a yield of from approximately 75% to approximately 95%.
