PROCESSES FOR THE PREPARATION OF 4-ALKOXY-3-(ACYL OR ALKYL)OXYPICOLINAMIDES

摘要

A fungicidal 4-methoxy-3-acetyloxypicolinamide may be conveniently prepared in processes that include the coupling together of 4-methoxy-3-acetyloxypicolinic acid or 4-methoxy-3-hydroxypicolinic acid with a key 2-aminopropanoate ester derived from a 1,1-bis(4-fluorophenyl)propane-1,2-diol.
