A series of Birch reductions on 4-methoxybenzoic acid is described. The results obtained were from an extensive variation in the reaction parameters including reaction times, quantities and types of reagents; e.g. the use of different alkali metals (sodium, lithium), the use of methyl iodide in place of the normal proton source (ethanol). The examination of the products was pursued with particular interest in the fate of the 4-methoxyl group which was found to be cleaved completely in each reaction. The preliminary results obtained indicate that this cleavage occurs very early in the reduction sequence. The work on the examination of the products obtained is also described.
