"processes for the preparation of 4-alkoxy-3- (acyl or alkyl) oxypicolinamides". The invention relates to fungicidal 4-methoxy-3-acetyloxypicolinamide which may be conveniently prepared in processes including coupling to 4-methoxy-3-acetyloxypicolinic acid or 4-methoxy-3-hydroxypicolinic acid with a 2-ester. aminopropanoate derived from a 1,1-bis (4-fluorophenyl) propane-1,2-diol. |
