Modification to Synthesis of Methyl Diantilis

Full Text
After we published the “Synthesis of Methyl Diantilis, a Commercially Important Fragrance” (1), we encountered a problem with the catalyst, Amberlyst-15, used in the second step. It appears that in some cases soluble acid impurities wash off of the solid catalyst and decompose the final product when the solvent is removed. This problem is solved by adding 0.5 g of sodium bicarbonate before the final filtration. The revised laboratory procedure that includes this change has replaced the original supplement available at JCE Online (2).
