Disclosed herein is a method for making compounds having structural formulae (I) of (II) wherein: X is (a) phenyl; lower phenylalkoxy; phenoxy; or benzyl; or (b) one substituent from group (a) and one or more substituents selected from C1-c4 alkoxy; hydroxyl; halogen; lower alkyl; and lower alkylthio; or (c) along with the phenyl to which it is attached, forms a multiple fused ring heterocycle such as dibenzofuranyl; Y is H, C1-C4 alkanoyl, C1-C4 haloalkanoyl, dialkoxyphosphoryl, alkylaminocarbonyl, haloalkylsulfonyl, or C1-C4 alkoxy carbonyl; and R is H, C1-C6 alkyl, C1-C6 alkoxy, C3-C6 cycloalkoxy, haloalkyl, alkoxyalkyl, arylalkoxy, alkenyl, alkylthio, alkoxycarbonyl, alkylamino, heteroaryl, arylalkyl, haloalkoxy, aryloxy, or C3-C6 cycloalkyl; and Z is or S, wherein the process consists of the steps described herein.
