PURPOSE: To prepare a compound useful as intermediates for synthesis of microbicides.
CONSTITUTION: This compound of formula I (Z1 and Z2 are each H, a halogen, hydroxy, a 1-4C alkyl, a 1-4C alkoxy, phenoxy, nitro, cyano or the like; Z1 and Z2 together with phenyl may form naphthalene; R3 is H or a 1-12C alkyl) is obtained by reacting a substd. O-tolyl acetate of formula II (U is a halide, benzenesulfonate, acetate or the like) with a benzoyl hydroxyamine of formula III (Z3-Z5 are each H, a 1-6C alkyl, a halogen, hydroxy or the like) optionally in a diluent (e.g.; acetonitrile) to give a benzoylated 2-amino-oxymethylene phenylacetate of formula IV, and then saponifying the compd. of formula IV with an acid (e.g.; hydrochloric acid) in an alcoholic solvent.
