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. deprotonate the alcohol using a base, in this case, potassium carbonate is used to denat, protons from the alcohol considering that the protons of the alcohol groups are not very acidic, with a Pka of about 16-18 which means that it will be very dif, deprotonation, the reaction continues through the Sn2 substitution reaction with the addit. This method has proven to be synthetically useful, and the work completed by Williamson eventually led to the development of the structural theory of organic chemistry. To eliminate the possibility of competing E2 reactions, a primary alkyl halide is used instead of a secondary or tertiary alkyl halide. $ 59.00 $ 29.00.
