| titleOfInvention | Preparation of higher alkyl esters of carboxylic acids |
| abstract | Larger (C6-C12) esters of substituted 2-pyridinyloxyalkanoic acids, such as 1-methylheptyl (4-amino-3,5-dichloro-6-fluoro-2-pyridinyloxy)acetate, are prepared in high yield and purity by first preparing the methyl or ethyl ester and then transesterifying with a C6-C12 alcohol. The methyl or ethyl ester can be prepared by alkylation of an alkali metal salt of 4-amino-3,5-dichloro-6-fluoro-2-pyridinol with methyl or ethyl chloroacetate and the transesterification can be carried out in the presence or a tetraalkyl titanate catalyst. |
