Page/Page column 19-20; 22, (2010/04/06)
This invention relates to process for preparation of Triclopyr, Triclopyr- butoxyethyl ester and its intermediate viz. 2-butoxyethyl chloroacetate. Triclopyr is prepared by hydrolysis of its alkyl esters. Triclopyr- butoxyethyl ester is prepared by reaction of triclopyr and 2-butoxyethanol in presence of a catalyst. Triclopyr-butoxyethyl ester is also prepared by transesterification from alkyl esters of Triclopyr. 2-butoxyethyl chloroacetate is prepared by reaction of chloroacetic acid and 2-butoxyethanol in presence of a catalyst.
