A process for making intermediates of the formula
wherein:
Z is phenyl or naphthyl each optionally substituted with up to 3 of the same or different defined substituents, and
R is H, (C1-C10) alkyl, (C3-Ca)alkeny), (C3-C8)alkynyl, phenyl, naphthyl, phenyl (CI-C4) alkyl, naphthyl (C1-C4)alkyl or each of the last four groups containing up to 3 of the same or different defined ring substituents, for the preparation of certain fungicidal imidazoles and triazoles comprises (1) reacting an arylacetonitrile of the formula
with an epoxide of the formula
under basic conditions and (2) hydrolyzing the resulting gamma-iminobutyrolactone produced thereby to yield the desired compound, wherein Z and R in the above formulae are as defined above.
