07 - 074A Selective Method for the Preparation of Aliphatic Methyl Estersin the Presence of Aromatic Carboxylic Acids. — A mixture of2,2-dimethoxypropane and methanol in the presence of catalytic HCl, generatedin situ from TmsCl, is found to be an efficient reagent for the selective monoes-terification of aliphatic carboxylic acids in the presence of aromatic ones. Asuccessful application of the method to the synthesis of various aliphatic estersis presented. Aromatic and heteroaromatic acids [cf. (XVI)] remain nearlyunchanged, thus proving the results obtained with dicarboxylic acids of type(I). — (RODRIGUEZ, A.; NOMEN, M.; SPUR, B. W.; GODFROID, J.
