Procedure
In this example the product was prepared in two synthetic steps. In the first step 4-methyl-2-pentanol was reacted with 50% molar excess of oxalyl chloride. Upon completion of the reaction the excess oxalyl chloride was stripped from the product at reduced pressure to produce 4-methyl-2-pentyl chlorooxalate having an assay of 96.2% and in a corrected yield of 88.2%. In the second step 4-methyl-2-pentyl chlorooxalate was reacted with 3-hydroxy-1,1-dimethylbutyl hydroperoxide in the presence of pyridine to yield the product as described below:
