Risk Statements- Semi-Microscale Williamson Ether Synthesis and Simultaneous Isolation of an Expectorant from Cough Tablets Stabile, Ryan G. ; Dicks, Andrew P. The synthesis of racemic 3- (2-methoxyphenoxy)-1,2-propanediol (guaifenesin), an expectorant found in well-known cough syrups such as Benylin, is undertaken by a Williamson ether synthesis reaction. Continue rinsing. Purpose- Mole of Acetaminophen: (1.31g / 151.16 g/ mol) = 0.0086 mol, Mole of Ethyl iodide: (1.81g / 155.97 g/ mol) = 0.0116 mol, Phenacetin molecular weight: 179.22 g/mol, Theoretical Yield: (0.0086 mol x 179.22 g/mol) = 1.54 g, % Yield: (0.613 g / 1.54 g) x 100% = 39.81%.
